She now has 2 1/2" true dual exhaust going throu Thrush turbo mufflers and Heddman Headers.  A 4160 750cfm Holley , Speedpro roller rockers, all new accessories, even the a/c which i haven't had in over a decade. A Powertrax LockRight in the rear with 3.42 gears.

New toy... Line Lock

The first time I used at my buddies garage, I roasted through 45k of tread, popped one tire, made the people in the building run out because they thought the building was on fire, and got a ovation from the local fire department that got many calls for a fire. Luckily I do electrical work for the Lieutenant so I didn't get in trouble, LOL oh ya and I did some electrical work right after that for one of the mechanics for a couple of tires so I could get home.

Its Big, Its Old, Its loud, Its Ugly and its perfect.

Oh Yeah a word of advise, stock driveshafts with 250K miles on them don't last long at 135-140Mph. The driveshaft broke not the U-joints!  Ooopps

What did you do to the trans crossmember for dual exhaust? It looks like you kinda chopped off the flat side and welded on an arched piece. Cool sleeper, BTW.

Nope that was not a stock 307 it had high comp (9:1) and a much larger camshaft (.200 lift verse .444 lift).

howd u get it to 309hp thats not a stock engine is it? iv got a 1989 caprice brougham Ls and the stock 305 only gets 170hp. im like muscle cars but the caprice shouldv came with 300hp. and no less. these cars are too big and heavy for just 170hp. its like a big guy with a little week heart.
