79 Wagon - Love my wagon, but I've dumped so much money into the car and it still doesn't have that "holy sh... this car is fast" feel. I mean it's a stout daily driver, but I expected more I guess. Here is the build list and all of it is new with about 800 miles on the new motor & trans to date.
GM 350/290 hp crate long block (Camshaft lift is .450 intake / .460 exhaust. Camshaft duration at 050 is 222 degrees intake and exhaust. Lobe centerline is 114 degrees)
Replaced GM 76cc heads with Aluminum Promaxx 2169 Heads : 185cc intake - 64cc chamber - 2.02 intake/1.6 exhaust
1.6 rocker arms
Edelbrock rpm air gap intake
Holley 670 street avenger carb (plugs say jetting is spot on)
Hooker headers - no cat - glasspacks 2.5in all the way back
New TCI Street Rodder TH350 Trans
original 2.73 gears in back (Don't really want to change as I'm on the highway alot)
initial timing is 14deg at 650rpm
solid motor mounts
I feel like I have to be making really decent horsepower and the motor feels strong, but it just doesn't have the oomph that I would expect from this build. Is it wrong to assume I should be more impressed if i'm getting 10-13mpg or is it the weight of the car that's making it somewhat lackluster? I know I'm going to read alot of "change the rear gear to 3.73", but I really can't do that and go even lower than 10mpg as this is my daily driver.
Drove around (slowly) for a year with the original 200cid v6 and this is way better, but the $$$$ to fun ratio I'm at is disappointing.
Any thoughts?
