Question 350 or 383. Naturally aspirated or turbo?

[Charliecharles]

Ok. I just cant decide. As the title says, im waffling between either keeping my ‘76 C3 a 350 or stroking it to a 383.
Then i cant make up my mind if i should go high compression flat top piston and naturally aspirated or go dished with plans on doing twin turbo. Any thoughts??
If i turbo i will definitely do twin turbos. Because i want to keep the side pipes.

Right down what you want to do with the finished project. Write down your budget. Right down your timeline and decide. But when you do decide.....Go big!

What have you done to your suspension, how's the frame, wheel/tires, brakes etc. More power is fun but if your existing components are not up to the task it can get you into serious trouble. I went the 383 route, newest engine is a ZZ383 Deluxe. It is a fun engine with a very flat tq curve. I bought this engine 3.5 yrs ago, $5550 delivered. GM later rebated $900 cdn for over stating hp/tq. It was originally mkt's at 450/450 @ 4500 rpm. The $900 was to avoid a class action suit, use the $ to by new rockers and accept that it all came in @ 5400 or 5500 rpm. In the end a fantastic engine with 2 yr warranty for @ $4600 cdn.near the end of its 2nd season I started going through oil - read on a Chevy forum that the culprit might possibly be a lack of sealant on some of the intake bolts - sure enough 2 or 3 had no sealant from the factory and the oil was working its way into and on top of the intake. No oil useage once I corrected this omission.
Before I had decided on this engine I looked at LS3's and at one point seriously considered dropping a Buick Gran National V6 turbo in s I had met someone years prior who had done this and ran 1/4's.
If you go twin turbo, where are you outting them - I've seen a few put near the rear of the car.
For me I opted for an engine that looked original, pretty much a drop in and I could existing pulleys, belts, hoses etc.

What are your plans for the vette - cruiser, 1/4's, combination and how much fabrication can you do yourself.
