I got the extrude for a steal on e-pray. I took a gamble and it paid
off. I don't have the numbers to back it up, but you can feel it in
you seat. To have them extrude it cost (at that time) $250 each part
plus shipping. This guy I purchased it from was running in the stock
catagory and had to keep his intake stock. Anyway I got it for $150
upper and lower shipped to my house. I took it to a machine shop and
had it plained just incase (another $45) and it has been great for 6
years. According to the nubers in 5.0 mag at the, the stock extrude
honed was running the same volume as the stock gt 40 (except one
runner). I have been happy mainly due to what I didn't pay for the
service. If I was buying one I would just go with larger runners
(Holly) and not worry about the extra 15-40 flow numbers.

My 88 lx was strong but and auto. I had to put 3.73 in the rear to
wake it up. Bought it for 9k drove it for 100k more, sold it for 3k
with 120k miles on it. Never had to repair engine, did have the trans
overhauled at 45k under warranty.
