Re: my 4.3 cam/intake/head build

Well I have not updated this in a long time. Well I have had a few problems but rite now she is running good. Right after Christmas we are going to tune it onthe dyno. It just has a safe tune in it now. Still running alittle rich. But here is the finished exhaust. First the tail pipe then the Elc cut

Re: my 4.3 cam/intake/head build

Oh and ur running a cat.
I got those same headers, no cat and the Hooker.
Im sure the cam makes a big sound difference too. So did the heads have to be machined at the guides for the lift on the 270 cam?
What did he do to the tune to get the idle smooth and whats the AFR?

Re: my 4.3 cam/intake/head build

yea i have to have a cat here because we have to meet emissions inspections, it's tuned out but is there lol. and you dont have the machine the head at all to run this cam i have, you can run the comp-cams push tubes: 7808-12, comp-cams 787 retainers, comp-cams locks: dont rember the part number but they are 7 degs, and ls6 springs. you dont even have to pull the heads but i did so they could be worked, and different valves were installed, and i dont know on the tune, my buddy builds ls motors for a corvette racing and other other large race groups so he knows his shit, in that video it was just a safe tune so i could work all the bugs out. right now i am driveing at about 14.3 afr and WOT at about 12.5 afr but he was playing it safe till we dyno it, i have been staying out the throttle because it's running so rich. he did a little playing around on it the other day when we were doing data logging on the street and now my idle is at 575 and it sounds mean lol

Re: my 4.3 cam/intake/head build

well i have most of the small problems taken care of and have 4k on the engine now and i hope get it the rest of the way tuned soon, we did a little driving around town tuning because the dyno has been tied up with there race cars. got the idle down more and little better air-fuel mix, still alittle rich on the top end but i drove to layed out at the part this weekend and it was a 580 mile trip with no problems, i got 23.6 mpg and that was a lot of mountain driving. and i have a heavy foot lol.

here is a quick video if the idle.


got a little pin striping done too



then had a little problem and now have no roll pan

Yep and after tuning should be better so it's not running so rich. And is your 4banger a auto? My dad has a 2.2 5 speed and gets close to 28 all stock

Re: my 4.3 cam/intake/head build

My bad, I met a lot of people this weekend forgot some names haha. Yea I used to own that blazer a couple years ago. It was in pretty bad shape. I did what I could with it when I had it but it still needed a lot of work to be safe on the road.

Re: my 4.3 cam/intake/head build

I was looking for information on putting 2.02/1.6 valves in the pair of marine 4.3 heads I am building and came across your thread. I have to tell you thank you for all of this great info!
I have a 2001 Xtreme 4.3 with a Wynjammer 10lb system, running his 36lb spyder injection. My engine is still factory stock, but the rest of the truck is complete as far as modifications for drag racing. Now it's time for engine modifications. I was thinking about building an Edelbrock 2114, but now that I see your thread, I like the idea of the marine manifold. So what if it's cast iron, only the base is. You already offer all of the detailed info about fuel lines and all! By the time I'm done with an Edlebrock, the price would be double what I can get a complete Ebay marine manifold for. I would have to replace the stock marine injectors with 36lb, and do some minor porting, but that's about it. Again- thanks for this info, including the rewiring ideas. I was going to start doing the same. I will be referencing this thread and may have more questions.
Thanks!
Great thread!

Re: my 4.3 cam/intake/head build

no problem. the system is more on the budget side over the Edelbrock 2114. if your interested you can pm me because all my stuff is off the truck and im going with a ls motor lol. its all ready set up and you'll just need to have the injectors sent off and rebuilt or replace them. i spoon a main barring and the motor was not able to be fixed. i started a rebuild with a turbo setup but lost motivation lol.

Thumbs up Re: my 4.3 cam/intake/head build

I just received my marine new intake assembly, Ebay for $324. A lot cheaper than the 2114 route, but HEAVY!

Anyway, I noticed the MAP sensor is a bolt-down type and my S10 2 BAR is from a blown Cobalt, recommended to be used with my Wynjammer. Can my friction-fit grommet type Cobalt MAP sensor be used with the Marine intake? I have not removed the marine MAP yet.

Also- I will need six 36lb injectors (my Wynjammer-sourced spider injection has 36lb now). Where can I get them, and are they standard Hi-impedance injectors in the marine intake? Do you think Summit Racing will have them?

Thanks for the fuel line fittings info. I think I'll replace mine down to the fuel filter area. I just had my trans out to replace the converter with a Huges 3500 stall billet version, and I saw how the lines are routed.

Re: my 4.3 cam/intake/head build

for the map sensor i taped a 1/8" npf fitting in then just ran a vac line to the sensor mounted on a bracket off the the side. with boost you don't want a weak point and that will be one.

for the injectors i am running the ones that came in the intake "27lb" and was planing on jumpping to 60lb when doing the turbo. the guy i got the turbo from was running 42lbs on 10 psi and was maxing out on them. you can go bigger and it wont hurt "to a point" but you tuner needs to know all the data so they can be tuned right. green top ford injectors are in it (42lb) gt500 ones (47lb). try to get a oem brand injector or one that can offer all the trim info.

my plan was to go all the way to the filter and that but i was in the air if this system was going to work fo i tryed to keep most of the stock parts lol.

locks


retainers


head gaskets on and ready for the heads


all new head bolts




now the heads. there's who know how many hrs into these, special thanks to my buddy rick for getting these dialed in. they are fully port matched and flow tested so they all match, they are a pice of art lol.







new intake gaskets, i like to use the gm updated ones, $38 and well worth it for me



lower intake set, it had the runners cleaned up and there was a large ridge that was removed.


getting stuff put on


the ls1 tb before i cut off the linkage arms


cut off the arm of the stock 4.3 tb and wekded it onto the ls1 tb, i have to use a tb spacer so my cruse control arm dose not hit the fuel rail, i may mill .50" off to lower it a little.


because the o-ring for the throttle body on the 4.3 intake will milled into the intake and the marine intake is not because it's on the throttle body i was left without a gasket, found a 96 gm vortec 454 tb gasket worked well.



installing the headers and they fit so good, i am really happy with them, tone of room for the spark plug boots




Can you explain what "large ridge" in the lower intake manifold that you had removed? I just purchased a new marine intake manifold assembly. Are you referring to that step at the top of the intake port right by the injectors? That looks restrictve...

You had mentioned earlier in the thread that your friend had "removed a large ridge" in the manifold base when porting it. Are you referring to the step at the port roof right at the injectors? I have my new marine intake and that was the first thing I noticed. I can't find any information as to why that ridge is there, and wonder if removing it will interrupt the fuel spray pattern or something else that would hurt performance. To me, that ridge will hurt flow since the top of the port is where flow would be greatest.
Any input would be appreciated.

you don't want to mess with the ridge around the injectors because it there to help with the spray of the injectors, in this pic toy can see were it was ground down. there was a ridge at the tip of each runner port. i rounded them to help with flow.

Thanks for that info, I can see where that step at the injectors will increase velocity and create turbulence to help mix fuel/air before the valve.
I haven't opened my manifold up yet to see the top ridges you are talking about, but I plan to do the same as you did to mine.
Thanks.
