Hi all this is my first post. Hopefully I am doing this in the correct spot.
I have been building cars and engines for about 25yrs. I have been out of the garage for the last 8 yrs (big family) and I am slowly getting back into it.
I just bought a 1985 ext. cab s10. It has a rust free body clean interior and all new metal box. It has a 350sbc /th350 trans... Un fortunately I will be downgrading it back to a 4.3L
I know a million reasons why a 350 is better than a 4.3 but it all boils down to this.
I have a 16yr old son (soon to be 17) and he needs to be able to drive it.
I would have no problem with him driving a V8 S10 (my first car was a 1968 Beaumont (chevelle) with a 350hp 396)
However no insurance company will touch us to insure the truck. I have been refused insurance by 5 companies. (because my son is 17) So I will be building a 4.3L 2brl carb motor. (I was quoted $700/month with a 4.3l 4brl)
Because this really gets me angry I will be running a very stock looking 4.3L but it will have some guts. I'd love to get 300hp, but I can see from other posts that most people think 300 is very hard to get out of these motors.
The last V6 I built was in High school it was a Buick 60 degree block and we got it dyno'd at 280hp with modest upgrades.
To make my challenge an even steeper hill to climb I'd like to stay carbureted. We have E tests and if you are running a newer motor they can force you to meet the emission laws of the yr of motor... so no PC. (as the emissions are plug in and pass/fail only tests)
So I have a choice of motors. I have a 1998 Vortec (running) for $150. or I have an 87 recently rebuilt for $100.
Both I feel are good starter cores. the only thing I am worried about is the balance shaft in the 1998.
I think the 98 has better head flow. but an aftermarket intake (carb) will be tough to find.
I want to run a 4br Edlebrock RPM intake with a 2-4brl carb adaptor. and run a 500cfm 2brl carb. Similar to a circle track motor I guess. (it has to look bone stock.
Any advice as to which motor is the better buy (pros/cons of the years) (I am assuming both motors a mechanically sound to start with)
Thanks
Jim
