Help me build my street Beast

I am redoing my project once again (i wrecked it after the v8 swap). I was wondering what would be a good setup for street driven daily driver running a th350 trans. Ive got a 355 right now, mild cam, stock bottom end, flat tops, roller rockers, reworked vortec heads, torker2 intake, edelbrock600 vacuum secondaries, hedman shortys and dynomax bullets but changing to dymax x-flo. Just curious what a good rear end ratio would be and if any, what should i change on the motor. I want as much power possible (who doesnt) with what im working with give or take a few minor modifications. Thanks -Tyler

Re: Help me build my street Beast

Bigger cam maybe... do you have the stock torque converter in the trans. or is it a stall? Might port and polish the heads. I'd get rid of the Edelbrock carb. and get a 650 Holley. Maybe try a new intake... the Performer RPM Air-Gap intake goes well with the vortec heads.

Re: Help me build my street Beast

I would go with full legth headers and a more agressive cam. There's nothing wrong with the Edelbrock carb, just go through the setup in the owners manual.

Re: Help me build my street Beast

What is your budget? The engine I've built for emann01 is a daily driver and is making some big numbers. I can help you with any combintation, but I need to know what budget to work with. Horsepower is a product of money.

I would like to build around the same hp as i have now 370 375 that was a dyno run about 1 1/2 years ago from the origonal owner. I have drove the piss out of the truck and it needs freshend up. its 60 over now and the block is not going to be useable. im not 100% sure to the internals, although i do no i have forged pistons a huge cam and a deacent set of cast heads with large valves 2.02 ect My goal is like said 350 400 hp range at the back with forged internals i would like to put her on the bottle, no more than a 125/150 shot to make close to 450 hp. its in the process of a back half as well as a built 9'' and 4 link with. Keep in mind i would like to keep a deacent budget and perfer not to build another 383. ANY IDEAS?

Re: Help me build my street Beast

Ok, now my turn.

Im going to be working with about 500 right now, limited on money cause im working on EVERYTHING. This is the cam i have right now. http://www.summitracing.com/parts/SUM-1105/
Also, It has summit hyperutectic pistons, stock rods and crank, summit pro street harmonic balancer, "high volume" oil pump, stock pan, roller timing chain, harland sharp 1.5 ratio's, stock pushrods, hyd. lifters, 2.02 1.6 valves, Edelbrock torker 2, hedman ceramic shorty headers, edelbrock 600cfm. Thats all I can think of off the top of my head. When I pulled the spark plugs, they were covered in burnt oil, I dont know how it ran as good as it did. Also, the tranny does still hae the stock stall. I had in mind a Lunati VooDoo Duration 262/268, Lift .468/.489, different intake, and dynomax x-flo muffler. Any input? lmk. Also, im willing to trade some parts if someone has something i could use just fyi. Thanks -Tyler

Re: Help me build my street Beast

if yall are lookin for more power all i have to say is STROKE IT! haha bcpd 03 idk what to tell you cause it sounds like you have plenty of stuff that motor should be puttin out more than 375 hp i have a 350 crate motor with heads and a cam pushin 400+ hp you could spray it but im sure thatd be a pain. and why is it you dont want to stroke that bad boy? haha you could also supercharge or turbo but those are not recommened if your on a tight budget and like the spray there a pain. id much rather stroke it but thats me ha

500 is going to be very VERY hard to reach with stock heads. Now if you have had them ported, you could get close. You're going to need around 290 CFM of flow through the intake port to approach that number. Also, your cam is a bit too small to allow good flowing heads to reach their peak.

Was 500 his HP goal or his budget?

Re: Help me build my street Beast

My bad...with a $500 budget, I'd just reuse everything. Have the heads reworked with a fresh valve job and new stem seals. Have the springs checked too. Assuming the bores are in good shape, just have them honed so the new rings will seat well. Don't go cheap on the piston rings. A good set of file fit rings or even gapless top rings will do wonders for restoring lost power and will help keep that power. If you have the money left over, you could step the cam up a bit. I've had good luck with the Performer RPM offering from Edelbrock. It's a split duration cam around 248 to 254 or so. Get the kit with the lifters. If your springs are questionable, the Sure Seat springs from Edelbrock are matched to that cam and will control the valvetrain nicely.

You shouldn't have any trouble with that much HP. Unless you can get a new block really cheap, you can salvage the 60 over one. Just sleeve it back to standard and go with it. There are as many opinions on sleeves as there are people, but I have never had any trouble with any engine I've installed sleeves into. While you have it apart, do a little gasket matching on your heads along with some pocket porting and you can imporve them quite a bit. With nitrous, the forged pistons are almost madatory. Not making any guarantees, but with the right combination of head flow, cam, intake and carb, 370 hp should be easily. I'd need more specific data on all of that as well as intended compression ratio to make an educated guess.

I'd have to agree to all this but I would add in a set of 1.6 rollers and an Air Gap intake. I've seen charts where the Air Gap outperforms the Torker.

thats a baby cam for 500hp.. go as close to a 300 duration and like a 550-600 lift imo and u need a set of dart or afr heads or trickflows are pretty good too

Re: Help me build my street Beast

but a $500 budget wont take u very far unless u pretty much want to keep it stock. the cam and carb and headers alone will be more than 500 hp...have 3523$ invested in a 383 stoker 500hp monster and im not even done yet...i still need the intake manifold, cam, balancer, carb, airfilter, vavle covers, and headers...picking up my block on wednesday...can wait to install everything

Hmmm... I didn't know you could pay for parts with HP...

Re: Help me build my street Beast

ive been reading on a easy way most out of a sbc with stock heads on a budget and the main thing i saw was vortec heads since u have them the next thing was headers which u have and intake which u have so the only thing u need for a 400 hp small block is the behive style springs and a good cam and watch out because the lift is limited on vortec heads but the forums ive read all say for a reliable torquey motor is the off the shelf gm performance parts hot cam kit try that with some 410 gears on 245's u can run 12's!

Re: Help me build my street Beast

You can get the guides machined for extra lift on Vortec heads. Anything is possible. But if you were gonna go with Vortec heads with machine work done, the more logical thing is to just buy a set of GMPP heads or aftermarket aluminums.
