Turbo 350 vs 383
Hey guys I’m currently building a SBC for my 88 fiero. I did the conversion with a stock 350TPI and I decided I wanted more. I went with an early 350 4bolt and upgraded to a new TPIS mini ram. I’m also going to be running a precision 76mm turbo, custom exhaust, etc. I’m using custom dished diamond pistons, Callie’s racing crank, truck flow aluminum heads. My question is do I go 383 or stay 350/355 as I’m running the turbo? And again this is going in a 2600lb fiero?

Re: Turbo 350 vs 383
personally I'd go with the 383. I'm not very knowledgeable about turbos, but my main concern would be reliability. seems like the 383 would just be simpler to operate, not to mention more low end grunt...

I hear ya but the turbo system is already built. I was trying to decide on staying with 355 or doing a stroker kit. The car will be TurboedTPI either way.
