Any pics with the rear lid closed? Looks like a nice job converting it!

This is the bugaboo with buying a finished or semi-finished car and the reason that I and others on this board build their stuff from scratch, so that we can engineer the whole mess properly, gaining max performance from the finished package.

You have no idea of the static compression ratio and how the cam relates to it, so you have no idea of how to alter components to gain the max from them. You have no idea of the squish and whether or not you will be able to operate on pump gas with optimal ignition timing. You have no idea if the torque converter is matched to the cam or if the motor has flat-tops with small chambers or domed pistons with big chambers or anything else about the motor.

Now, you have to understand that I'm the type of guy who would begin heart surgery with a hatchet, so I would tear the motor down and measure everything and find out what's what and how to proceed with making the whole mess viable. But that's just me. I wouldn't have bought it in the first place and I'm certainly not suggesting that you tear the motor down. I'm just saying that's what I would do if I had come into ownership of the car.

now that is unique.

Ok I have contacted the original owner an I am waiting for a engine build from him. so I was out tryin to lean the fuel in it. I had a budy of mine come out who knows alot about chevy engins an we couldnt get it to not run rich no matter what we did. it runs so rich that it burns your eyes after about 30 seconds of running in the garage. So he said the he would start with a carb rebuild kit since there is a massive dead spot in the throttle no matter how he had tried to adjust it we have the timing adjusted with a timming light. so I'll be rebuilding the carb this week. have to work a little on my other fiero an samurai too. If I dont get this sorted out before winter me an my buddy rocky are just gonna tear the whole motor down an find out what we have for sure an what we want to have. He also mentiond he knows someone with a blower that i might be able to convince to sell it to me for pretty cheap.
