That sounds like a lot of spring for a flat tappet. Is the cam or lifters specially hardened? Not criticizing hear, just haven't heard of that much spring on flat tappets.



Yes they are hardened...I am told, they really don't need a break in , and I can go cam to cam with them....Apparently, they have logged many thousands of street and strip miles on these with very good results and little to no failure in a lot of big inch Hemis...Give him a call if you don't believe me. I have a friend that lost his 493 at the end of the season due to a roller lifter failure...I am not going there. My buddy is running it in his 572 hemi, so it can't be that bad.

New carb showed up....And I picked up the new intake...Its big!
