Motor mock up

Post by **Maddawg** » May 4th, 2009, 10:14 pm

Hey all. Was wondering what the thought was of mocking up my block & head to determine my pushrod length( pistons being dished currently). Heres so far .004 deck height, .044 HG, .004 shaved off head(need to double check that with shop). This way I could order rockers & rods for assembly this weekend.
Thanks Dale

I'm going to run up to Summit & buy one, was wondering about putting shims for HG, basicly a mock up (until I can fully assemble when pistons are done) so I can get rods ordered. Since I'm using standard rods & lifters I believe this should get me close enough to order them.

Its always a good idea to do a mock up... Since it sounds like your in a time crunch, your idea seems fine since you cant actually put the head on yet.

If it were me i would wait untill i have the head on, and then start measuring etc.

The problem with those pushrod checkers is that you need some way to measure it... I don't have a caliper that larger and my machine shop didn't either. I went with this one: http://store.summitracing.com/partdetai ... CCA-7704-1 It starts out at 8.8" and each rotation equals .050".

thats not a bad price and im sure i could get a caliper from work to measure, but not quite there yet

I was looking @ that one as well & trying to decide.

Use a pushrod checker. The one I bought was from comp cams. I think it went from 8.800 to 9.800. One turn equals .050. Use the measurement from the pushrod. Do not use calipers to measure the pushrod checker. Your measurement will be off. Check out this link. On measuring pushrods: http://www.trendperform.com/measuring.html

Also, keep in mind that there are 3 different ways to measure pushrods.

what are the three ways silverxj?

Don't mean to jump in here, but buy a length checking pushrod and order what ever size it says you need. That is what I did and it worked. No math or guessing you are ordering the right length. Trend pushrods were the cheapest I could find, quality is excellent and fast shipping. I used a comp cams pushrod checker. Trend also sells one for the same price. It was well worth the $20.00.

Jump in the more help the better. Ok so which of the 3 are correct? I think I'm missing something here!
