Possible new Class build - need opinions

I wonder if the 6 cylinder would be better, or maybe even an earlier year with a carb instead of the TBI? PFI might be better, but harder to find this cheap..Guy only wants 600 bucks for a complete car.

I guess that this would all depend on what you're comfortable dealing with. There's plenty of info available on any of the V8s so are you more comfortable with a carb or FI? With the 4 or 6 cyl., you're going to be pretty much on your own.
For $600, I'd be buying the car anyway. Check the lower cowl and the rear frame and wheelwells for rust.

I’m attempting to complete a 6 cylinder project, but I’m concerned that I can’t get enough HP out of the cubic inches available. Basically I don’t know that I can get to 1.3 hp/cubic inch to mathematically get to the index. I would think it would be much easier to run a 302 V8 which is factored the same as my V6. They already have 30% more cubic inches, no mind the additional torque.. Either way I guess I’ll still be able to bracket race it on Saturday night..

The hurtle with TBI is injector size. Once you get to the point of needing more fuel there is nothing larger available. Am sure the TB will flow plenty of air fuel demand needs to be overcome.
