LM7 into a '66-67 Nova? I'm gauging interest in doing a LSx Swap in a '66-'67 Nova.
I think the motor mounts and exhaust shouldn't be too much issue.
Looking for input on Suspension, FI vs Carb, and Wiring Harness
The motor would be a small build. LM7 out of a 99+ Silverado tore down and cleaned up.. Maybe some forged pistons, (just in case
) a little cam, light porting to the heads. I think Carb'd would be more fun.
Transmission would most likely be a TH350. I'd love to go T56 but wouldn't want to cut up the floor boards.
Suspension - Street car. How much tire would fit under it without tubbing?
What's a general idea for parts list? Any guesses torwards cost (except more than budgeted
) assuming that the big things are already paid for (Car, trans, motor)
$2k for exhaust/intake/pistons/fuel lines/etc?
$3-5k for suspension?

Do you want to keep the stock front clip or go with an aftermarket replacement? You should expect to at least double your estimate for the engine/exhaust parts if you intend to replace the pistons, cam, and requisite supporting parts (valve springs, push rods). Your exhaust options are also limited and will not be "cheap".

Exhaust you can do one of 3 things:
1. Hooker block hugger headers ($200)
2. S&P Custom Long Tubes ($700)
3. Jegs header tube kit & LS1 flanges ($85+50) and weld them up yourself
As for the motor mounts there are a few companies that make adapters so that regular old SBC mounts will work. Most range in the $50 range.
Suspension go Caltracs they retain a stock smooth drive and flat out WORK! For the front suspension a full clip can be pricey at $2500+, but there is an alternate kit available that modifies the stock front clip. The Mini-Sub frame kit from CCP (base kit 399) comes with lower A-arms that eliminate the stupid rods and triangulate everything properly. There is a full kit that adds upper arms, shocks/springs, etc. for more.
For the tire you can fit a 255 wide out back in a 66-67' w/o too much trouble.
