Any idea what if any increase in power these will make on a fairly healthy 350 TPI car..It runs low 14's as is....Thanks very much...Tom

 

I had just bought a set and sent them back because I was shocked at how poor quality they were. I did not install them but the casting was very poor.

They had alumiumn slag all over them and very poorly machined surfaces. For a "made in america" part they looked like total junk to me.

 

These dont look to shabby, but the only reason i got them was i have a summit card.....lol............ANYONE used them???? Any dyno test??? Thanks...

 

do your self a favor....and dont waste money on tpi,,,,I was just like you and now my buddies have beaten the light into me....now I have dreams of short runners and OBDll. ; )

Actually the car is going to belong to a good friend of mine who wants it as a TPI car..I am investing the money from it in a carbed 383, for my 89, but I would still like to know about the runners..The car ran a 14.19 day before yesterday, we are just trying for a 13.99....

So if anyone has used a pair please let me know...They are already paid for....Thanks, Tom

 

I have a fully ported SLP set that im selling on here for $300 shipped.
