Tunnel ram 440
That's badass. I like the hilborn scoop too. Is there a way to check them?
I haven't own the car for a good 5 yrs., the new owner painted it & did a few things on the inside, he just recently installed a pair off 660 center squirters & loves em. I ran V stacs on it, he installed the hilborn, I made a good 250 passes in that car after building it, ran a best of 10.87 @ 123.58, that was on a very slow 1.62 60ft., & it was still a bit lean on the carbs but pulled like a mother on the big end., i sure miss that car.
You can get a spring tester, if i'm not mistaken they can be checked with the head on, are the heads bolted on yet??. It'll have a dial indicator & pressure gauge, you can check what it is "right off the seat" & at say .500 lift, then check to see how far it goes before the retainer hits the guide boss, You'll be fine with the stock guide boss height with less then .500 lift., but i would recammend installing the proper springs if those are stock replacement units, its not hard to do really.
