It has been a long time coming but I was finally able to get my 1986 vette swap with the 427 completed over the winter. For those who do not know the car has not run since 2014 and this winter I got it mostly completed. The basics of my combination are listed below:
-1986 vette
-Full street interior and car is at full weight of 3473 LBS as raced on friday night with the driver
-427 LS7 with a stock bottom end but has a LS7X texas speed cam 248/256 @ .050 with .624/612 lift
-Melrose headers
-2000 camaro computer running the engine and 4L60E transmission with 4500 stall and lockup
-3" dual exhaust system
-Ford 9 inch rear conversion with 3.73 gears
-275 drag radials
-4" maf sensor
-Engine makes around 650 to 700 horsepower
-Full cage certified to 8.5 ET's tucked nicly in the car so you can not really even see it unless you look

I have a tune mostly dialed in, there may be some additional power hiding in there but not a lot

The car looks like a sleeper, looks like any stock C4 corvette and at the strip you can barly hear it run compared to most of the cars there.

I dynoed the car on a Mustang dyno in the unlocked condition with a conserative tune (Rich and pretty conserative timing and the car made 510 RWHP at around 6900 RPM but it was still climbing and I lifted to make sure I kept all the parts inside the engine. Dyno sheets attached.

It was in this condition that I ran the car on Friday night and the car ran well, the DA was 1700 ft at it went a 10.22 ET at 131 MPH. (I was hoping for a 9 but I can live with what I have)
Car was very conststant I ran 5 times at it ran between 10.22 to as slow as 10.25. It also pulls a nice 6" wheely at the launch.

Run attached:

 

Awesome work and very cool
