how much would these mods in a '94 Z28 be putting to the wheels.(estimate of course) Mac Headers(ceramic), Off-Road Pipe,
Flowmaster, Thermostat of 180 Deg., K&N Filter, Bigger M.A.F Sensor. any help would be appreciated highly.

anyone esle have an idea other than his'?

I would't buy or not buy a car based an $9 thermostat

upgraded? i dont think you can really upgrade them

you can get a 160* stat that makes your car run colder., reduce engine life and gain you next to no power

i didnt mean i was not gonna buy it for that i was saying if that he lied about that he could have lied about other modifications thats all i was thining about but if that is all that cost and if a colder one makes it works then im happy its a 180 thermostat. as u can tell im new to the LT1's so i dont know about them much thanks for your help man you were very helpfull

ok... ill break it down

Mac headers - gain.. about 15-20 rwhp
off road pipe - only really making the car illegal in most states.. so you have no cat.. I say 5rwhp at the most!
Flowmaster - slight gain depending on model.. I had the 30 series which was a 3" in and single 3" out
T-Stat - HA!
K&N Filter - I found that they dont always perform better than stock. Check sig below.
MAF- again, not worth it..

So, lets say your car had 275 at the motor when new.. now you have age... I say you will dyno:
A4 - 245-255
M6 - 250-260
those are my realistic estimates.. Your largest bottle neck is your intake.. get a CAI kit and see some power.

thanks for the help guys. so is $6500 for an 94 LT1 Z28 with 86,000 miles on it worth it with those mods. is it a good price? fair? steal? any help would be appreciated thanks

Like My Taillights?

It isn't a steal, but it is a pretty fair price. Has there been any recent maintence work done to it recently, ie.. tune up, power steering pump, opti, water pump, window motors?? Do a search on these items and you'll find they need to be replaced peiodically, some people more than others
