Say you had a 66 vert vette. The car does not have the original 427 or tranny. So, now you really can't make a perfectly matching numbers car. What would you do for a radical build? To make the car a beast, a complete show stopper? What engine cube would you go with? Supercharger or not? The car has a bored out 70 model LT1 I believe. The car was aquired to my father after the death of my cousin who, he and my father liked to hot rod. The heads I have traced back to an original lt code from 70. The block I'm not so sure. My dad was thinking that they did a lot of bore to the heads with different valves and more work on the bottom half. I truely think the car has around a 377 or more. We know it is bored 60 in the cylinder walls, we just dont know the crank specs, connecting rod length, and cam size. The intake was a Gm intake I believe that went to an LT1. All of that evidence leads me to believe it's an LT1 engine dropped in with a few goodies. That engine I am thinking is too dangerous to run for cruises as it will prob run hot from the .60 bore and big cam. So, with that said, what kind of block? Maybe a Texas Speed 408, 418, or 427. I really want to run a small block rather than a big block. They're just not practical (sorry for the big block guys ). Also, maybe a nice little shot to boost for self gratification on a win. :laughing: I'd like this car to be ungodly. Now, to tranny, I already have a heavy duty rock crusher, and the rear is 373 factory. What all would you do to beef that up to make it hold?
