70-72 LT-1 upgrades?
Any suggestions on how to improve what many thought was the best Vette of that time?
I am thinking about making it a better street car, using parts binning and a few aftermarket parts. No major fabrication please.
I see where the post on better 350 didn't go far. lol
I'm thinking a car that can be driven hard and safely,
but not a race car.
A stk 350 w/better heads and cam would be fun.
How about starting out w/a few parameters?
350 rwhp max. After that things break.
Better handling than stk, w/ equal ride.
Man or auto overdrive.
I already have the removeable rear window.
What mods did or did not work for you?
TIA

as for the engine, the only thing i would recommend are headers, the advance curve set up, and maybe jetting the carburetor. might want to make sure the valve lash is right. it is a good running engine no mater what year.

TKO600 5-speed, major overall improvement.
- 2.87 first gear ratio, compared to M21 of 2.20, gives a major boost to first gear performance.
- .68 overdrive, nice for cruising, (low noise, high gas mileage)
Mild porting of the heads yields a nice performance boost. Cheap power if you do it yourself.

Restomod!
I was thinking more of turning a mid year C3, into a LT-1 Gen II.
Better engine, 5 sp, L88 hood, mini-flares and the VB&P catalog. lol
Don't forget better wheels/tires, reduce weight, both sprung and unsprung.
I wasn't advocating cutting up a collectors car.
I would like to see a bang for the buck special though!

Bang for the buck ,number one bang for the buck would be a supercharger.At one time i had a engine setup like a lt1 and all i did was put a small weiand 142 supercharger and it was just about the fastest thing around ,super fast ,quick.This would be the best mod you can do and the cheapest .you would have to go with a after market hood though.look at my avatar.You also will have to get a bigger carb or rejet your carb.100 hp power just bolting it on,a BIG seat of the pants feeling.

Yank the original drivetrain and store it. Drop in a 383, a TKO, and don't worry about breaking valuable parts. An LT-1 should already have 3:70's or 4:11's.
Get a nice VBP suspension kit and you have a bad hot rod. Plus you have the ability to make a stock LT-1 if you need to sell at some point.
