just what i want to drive. a fake ferarri

 

:Shrugs: I don't see anything wrong with having a kit car. I say go for it!

 

It's pretty nice for a kit car, but did you guys notice that the shifter looks like it would send your hand through the hvac controls when banging gears? Shorten that thing, it's not f-150, it's a f355 replica!!

 

Some people arent smart enough to understand that. Had the same discution on ls1tech.

 

Thing about kit cars is that most of them are either extremely cheesy looking (batmobiles), or they try to make something that looks like the real thing but it comes out looking half baked. I was just really impressed with the quality of that kit and the fact that out of all the possible engine choices out there, the guy chose an LT1.

I found a company that makes a F355 kit that's pretty authentic and well designed, and on their specifications page they state that in full street trim, the car weighs 2,850lbs. Drop an LE2'd LT1 in one of those and you'd be able to blow the doors off the real thing.

A car like that needs a LS7. If I had to do a LT1 I'd say a nice 355 with some huge heads and a TT setup.

I knew a guy who did a SBC swap into a Fiero. It was a 383 that put out around 450lb./ft. Main problem he had was keeping the front end planted whenever he punched it. (Not that this isn't extremely cool.) It wasn't very long and he started having body mounts coming loose and the body panels themselves were spider-webbing. You have to remember, in a Z06 the weight distribution is an almost perfect 51%front/49% rear, whereas a Fiero has more like 40%front/60% rear. A huge torque monster like an LS7 in that car, while I'm sure would be a blast, would probably do alot to shorten the lifespan of the kit. I think this might be one of the few instances where a destroked motor with a peaky cam might be of more benefit. (A 302 LT1 might be kinda unique.)

I wonder how a 302 LT1 with an aftermarket EFI setup that could handle the tuning requirements for 8,000rpms and breathing through a Tubi exhaust would sound....

 

Very good point. Now that i think about it most cars of this nature dont go with extreme engines. They usually go with something small that makes average power I guess because average power in a light car still screams.
