Matt, this is the 350 ci small block Chevy in my mate's cob.
Admittedly, it's not a modern LS1 or LT1 but it traces it's descendants to your Corvette.
Absolutely correct Steve - the 350 mouse-motor has been the staple in the Corvette since the mid-50's, with notable exceptions being late'60's big-blocks and the DOHC ZR1 engines.
There was much speculation about putting an OHC motor in the C5, but low hood height (for improved forward viz and low cd) demanded the push-rod engine. Interestingly, research with 'vette owners suggested that it was torque that was most appreciated, rather than hi-tech, high revving, peaky performance and the small block certainly delivers in this regard. Mid range acceleration is insane. Although only slightly modified, my car will drive away from my bosses 360 Modena from around 70mph and cost less than half as much. Not to everyones taste, but it rocks my world.
I imagine that tin indian has a bit of grunt too. A friend of mine built a Southern Roadcraft Cobra about 8 years ago. He put a Moline 400ci crate motor in it, with a Saginaw rock-crusher and it went like the clappers. You running a manual or a slusher?
