I'm doin a 383 with a cc306 1.6 rr and some behive springs. Anyone know what size push rods I'll need?

 

Lol!.

 

i'd guess a 5/16. width.

 

Wow I would expect this from the guys at ls1lt1. The length is what I was asking. Maybe next time ill be more specific for the simple minded out there.

 

to get the length you have to measure on your actual engine.

 

We are pretty simple minded. I mean any retard would know what length you need. I mean its not like silly things such as deck height, head gaskets thickness, having the heads milled, etc have ANYTHING to do with it.

In short: there is no answer to your question because there are still unkown variables. And even when you gave all the variables we STILL can't tell you. You need to measure.

Get yourself a pushed length tool, and research how to properly do it.

 

you'll need a length checker for that. use either an adjustable pushrod or a type of length checker that fits over your stud. either is fine.

simple minded? that hurt dude, really hurt.

 

So I can't go with what someone else might have on the same set up, I'll have to get the adjustable push rod to know for sure? If so where can I get one?

 

That was quick. Those where posted up as I was typing. Where can I get one?

 

If you were on an original motor with stock untouched heads that's never been apart on stock lifters, you would use 7.20" pushrods. But since you're not, no one can tell you exactly what length you need, because all that cool stuff Gregrob just posted needs to be considered. Get a pushrod length checker.

 

 

check out manley part number 42133. the are pretty slick. not sure if they work on ls engines. pretty sure they do though. summit, jegs, anyone should have them really. this is an alternative to an adjustable pushrod. though those are great too.

 

Thanks. I've found one on eBay that should work.

 

I would recommend picking up a Comp Cams tool. The cheap ones have been known to bend during cranking due to higher spring pressures.

EDIT: Or use lower pressure length-checking springs.

 

The one Im looking at is comp cams.

No, that's one thing that's specifically said NOT to do.
