Well I have a 2.8L V6 and need some advice. Whenever my engine goes (which will be a long time at the rate it is running; and hope it stays like that) I want to rebuild it now. This is what I was thinking and does it sound good and about how much do you think that I would be looking at price wise (keep in mind that the pulling and placing the engine will be done myself)? Here it goes: balanced, blueprinted, ported, polished crank, O-ringed heads, ForgedTrue custom forged pistons with full floating pins, factory high-output cam, valves, Crane aluminum roller rockers, chrome-moly pushrods. Sound good to you guys? About how much gain would I notice w/ all this stuff done? Thanx

Well, no one else took a shot at this. You might have gotten better response on the V-6 board.

But, it looks to me like what you'd have is a very healthy lower end, able to take much punishment. You mentioned porting, that's a crap shoot unless you find someone who really knows how to improve these heads. No mention of upgraded induction or exhaust. Power would probably be better, but not stunning.

Cost? Probably more than a 3.4l crate engine. Power would probably be lower than a 3.4l crate engine.

Say, perhaps you should consider the 3.4l crate engine.

You might get a better response on the V-6 board...

82 Berlinetta, orig V-6 car. Rescued w/86 LG4/TH700R with all harnesses, sensors, ECM, etc. 2.73 open. Cat-back from '91 GTA, Accel HEI SuperCoil. AMSOIL syn lubes bumper-to-bumper. Daily driver, work-in-progress (LB9 w/ZZ3 cam, exhaust, paint, etc.).
57 Bel Air, my 1st car. Currently 396 .030 over, Weiand Action+, Edelbrock 1901 Q-Jet, Jacobs Omnipack, 1-3/4" headers, TH400 w/TCI Sat Night Special conv & shift kit, 3.08 10-bolt, AMSOIL syn lubes bumper-to-bumper. Best 15.1 @ 5800' Bandimere. Daily driver while Camaro was being put together.

 

how about 3.8 litre supercharged engine used in buicks and pontiacs rated @240hp at 7psi boost could be modified to 300hp easy

 

I did basically the same thing only I used a 3.1

Balanced & blueprinted bottom end, ported and polished heads, intake, and exhaust manifolds (they don't make headers for the 3rd gen), CompCams 260H - 212*/212*@.050, .440", magnum roller tip rockers, springs, locks, retainers, pushrods. And rebuilt the 700R4 with a shift kit.

Total: $1,700

I could BARELY keep up with 305 Camaros!

Just swap in a 350, it's not as hard as people think. If you can swap a V6 for a V6 you can install a V8, no big deal.

I just threw in a Goodwrench350 in August, and now I can outrun just about ANYTHING stock (under $40,000).

Just my opinion,

John

 

you could get a buick gn turbo 6

 

I would go with GM's 3.4 upgrade. It's not "technically legal" due to emissions, but it should pass without any problems (stick with the don't tell policy). The V-8 swap can be done as well, it is a lot of work though. Unless you know a whole bunch about wiring and swaps, and have too much money laying around (I do take donations) you don't even want to think about putting a turbo buick in. Do the 3.4 with some type of centrifical blower. You'll be much better off.

Torque is KING!
All pray to the god of grunt! When ye thinkth ye has been whupped than shall ye meet the mighty Buick! For none can surpass her majestic power, and all will yet try. All pray to the god of grunt. For the King of torque has arrived!
1. 82 Camaro+ 1. 455" Buick+ 1. N2O plate = YOUR WORST FRIGGIN NIGHTMARE!!!

Mike, you haven't come back to respond to these answers. You might not like what you're hearing, but the things you are talking about are VERY expensive! They are even more so since you are doing them to a 2.8 (meaning it would cost more than it would to get these things on a 350).

Some things just don't make sense, either: Floating pins are for engines that are torn down between rounds for rebuild; o-ringed heads are for power-added engines (NOX, turbo, supercharger, etc.). Why would you do them to a 2.8?

Since you're saying you can't afford a bigger engine, it doesn't make sense to do all this expensive stuff that will end up costing more than a bigger engine.

See where we're coming from?
