Hi guys quick question on pushrod length.Ive got a 90 roller 350 engine and im using trickflow heads and need to know if i can use the stock length pushrods or if i need longer.Is there anyone else using this combo?

 

I have the 23* heads, not the twisted wedge ones and use the stock length. I did use an adjustable first though and verified that it was the proper length. Mock it up with stock ones and check your geometery.

 

ok thanx im running the same heads and just wanted to be sure i didnt need any exotic lenth pushrods trick flows sight doesnt have info on these heads anymore that i could find.

Shouldn't be exotic, but stock may not be right either.

 

here's info from the stuff that came with my heads: (TFS-30400007-CNC)

first before i retype the chart, be it known that i am running crane gold race rockers, with a comp cam roller cam.

i am using 7.4" pushrods, which are pretty much dead on for my combo. they also happen to be the suggested ones for that setup.

THE FOLLOWING IS FOR USING ROLLER ROCKERS: CRANEGOLD, TFS OR SUMMIT "BLACK" ROLLER ROCKERS.

for a standard hyd flat tappet cam, trickflow recommends 7.8"

for standard solid flat tappet, trickflow recommends 7.9"

for GM or Crane hyd. roller - 7.2"

for Comp Cams or Crower hyd. roller - 7.4"

THE FOLLOWING IS FOR STAMPED STEEL ROCKERS

Standard hyd flat tappet - 7.550"

stock GM hyd roller - 7.150"



Basically, i would get everything put together and figuer out the pushrod length before ya order em....

I'm running the LT4 Hot Cam so stock length would make since.
