need to use stock pushrods on alum. heads with guideplates... yikes!

Hi, i am in the process of putting my top end together after cylinder head swap and i forgot to get pushrods. now heres the kicker, i am moving in a few days to colorado from cali and i have to ship the car there. i am going to use the stock pushrods for now cuz all i have to do is run the car long enough to get on and off of the trailer. how bad is that gonna be on the motor? am i gonna do serious damage or will it be fine for that short of run time? i am going to get hardened pushrods asap after i get to colorado though. please any input will help thank you for comments in advance, max.

Wrong sized pushrods can cause a plethora of problems from loss in performance to engine failure. I wouldn't chance it, but thats just me.

does anyone know of a referance chart or formula to figure out what size you need cuz i tried one on it last night and it definately looked like the pushrod was too long.

when the valve is completely seated the rocker tip is supposed to be resting on the intake side of the valve right? about 2/3 to the intake side then at full lift 2/3 to the exhaust side? please correct me if i am wrong?

the only "formula" is a $10 adjustable pushrod checker and a hydraulic lifter converted to solid for measuring purposes...you cant check the pattern with a hydraulic lifter in place unless you swap a valve spring for a soft checking spring...thus the reason for the converted "solid lifter"

how did you plan on getting the proper length pushrods in the first place? by going on an internet forum and asking someone what length YOUR motor needs for YOUR specific combo?..wrong answer..

why dont you just get some neighborhood kids to push the car up on the trailer?...and measure the pushrods for correct length like a real engine builder would...

because im not an engine builder and this my first time doing this so forgive my novice questions...i don't have unlimited time or resources so, yes, i did figure i could work it out and if i had questions i thought a mustang forum might be an appropriate place to ask them and make sure i was doing it right. and the moving company requires the vehicle to run in order to ship it

Relax Maxy I think you need to get some thicker skin but you will usually get good advice here.

One thing is what type of head as that will very the pushrod greatly?

You might be able to get away with using an incorrect pushrod but too much or too little may hurt the motor.
