91 Camaro Convertible 355 LT1/700r4 with a Vortech to come this winter

To start with this is my dads car and right now the car is running in NA mode. I originally bought and installed the LT1 in my Camaro way back in 01 and used a Painless harness as back then there were only a few of us that even attempted the swap. Well after about 9 years and 15k I decided I wanted a 6 speed/ls swap so I sold my motor to my dad and his swap began. His plan for the car is a nice driver that runs really well. Here is a picture of the car when he bought it. He bought it off ebay for $6500 from a police officer in New York.

The car had a stock 305 TPI and 700r4 in it. It also had a drum brake rear end with 2.73 gears. It has red leather interior and was in great shape. To actually start the swap I had to remove the motor from my car and put some thicker headgaskets on it.

The block is a 4 bolt main LT1 block that has been bored .030 over and has speed pro pistons and plasma moly rings on stock rods. I ported and polished the heads and it has a XE 230-236 cam in it. The motor made 341 rwhp and 336 rwtq in my car before the thicker headgaskets through an automatic. I went from a .039 Impala gasket to a .066 thick Cometic gasket to bring the compression down a little. He plans to run 6-7 pounds on it. We plan to install the supercharger over the winter. So here is the beginning of it and we have plenty more to come.

That's a sweet ride. Looks awesome with those stripes painted on too!

So you're going to put in a Vortech supercharged ls1? That's gonna be fun ride when its done.

And how many miles are on the body?
