Inliners International Forums General Discussion Blown and Injected On a budget, Turbo or EFI first for stock GM 250?

I doubt the 292 will fit under your hood. I had a 250 in my 68 and looked into it. The 292 is substantially taller.

Take a measurement from the engine mount to the top of the air filter. Now measure the other engine. You'll find it's a couple inches taller. Now go get some play dough. Stick it on top of your 250's air cleaner and close the hood. When you lift the hood you'll know your clearance. It's not much.

EFI: look at FiTech. Plug and play for under a grand.

Turbo: Why not turbo charge your 250? You can get decent power out of her.

What budget are you looking at? Building an inline isn't cheap. Not at all, in fact.
