Im building a 402 stroker with the TrickFlow heads and Iv heard that you have to use a shorter push rod. Now iv heard its a 7.1in push rod and iv heard the stock length will work so which is it? thanks

You should always check but we usually end up with a 7.50 for most builds. Also get a 235 they make a bit more than the 225's from what we have seen. Just buy the heads from me and I will throw in a set of the right pushrods Hope this helps.

Mike, I thought we needed a 4.030 bore for the 235's. Can you use it on a stock bored LS2?

i was told 235's would lose to much down low for what I was doing, any comments?

Talk to Brian Tooley from TEA. He'll probably tell you to use the 225"s.

^^ Brian Tooley talked me into going with 225's instead of 235's

I figured he might. Good luck with your build

Just got numbers yesterday with my TFS 225's. 569 RWHP and 538 RWTQ. It made a lot more than any of us were expecting. And incase anyone is wondering if the numbers are played with, my car has been on this dyno several times over the last couple years on my old setup and has proven to be very realistic and was within 10 hp of another local dynojet.

Waiting for my graph to get e mailed to me since i don't have a scanner.

What cam?

Custom ground. 246/250 so it's really not that big compared to other 408's i've seen. lift is only 615. I figure if you're going to spend the money to build a 408 might as well spend the extra couple bucks to get a cam made to your application.
