What pushrods!!

[kwest88]

im putting vortec heads on my tbi and was wondering what length pushrods i need i think the vortec motors and the tbi motors had different length pushrods so which ones would i use

you need to measure to get the correct pushrod length. you might be okay with a stock length, but in order to ensure proper valvetrain geometry, you really need to measure for proper length for your setup. plus, doing so will ensure much better longervity and function.

Yep, just buy a pushrod length checking tool or ask a shop to borrow one. You could go with stock length, but its better to be 100% sure

The vortec had a different length because of the roller lifters. The stock length for the vortec is 7.200. I do agree the proper method is to check.
