First of all, thanks in advance for the help.

My buddy is intalling a GM ASA cam w/ specs 228/236 .525 .525 110 lsa, he is also installing stock unmilled 243 heads. Question is, are the stock 7.4 pushrods ok or does he need a different length. We have found a few diff. answers, some say stockers are fine, and one guy says we need to use a 7.425. I need a definitive answer please, looking to buy these today!
Once again, thanks!

 

Need an answer please!!

 

Stockers Are Fine, 7.425 Will Give You Added Preload If Needed.

 

Thanks, so is one length better than the other to use in this situation?

 

7.400's and call it a day.

 

I just put the 7.425 in and really like how it quited down the valve train !

 

7.4's are too short, you can use them but your prelaod will be jacked up. Its your call whether or not you want it done right.

 

We are going with the 7.425's, thanks for the responses
