Camshaft Questions

I just rebuilt my 2000 502, I live literally 2 miles from Summit Racing in Arlington and I dont have time to have a custom cam cut nor do I want the added expense right now. Maybe next year. So I prefer something I can just pick up off the shelf.

4.500 Pistons 3.8cc dome, which I think brings my compression up .5 a point. block is also decked roughly 10
088 heads with extensive exhaust porting and cleaned up intake side, with a 2.25 intake valve and a 924 spring
Im going with a Carb set up, I have plenty of options on carbs and intakes. So suggestions on what would work best would be awesome.
CMI Etops Exhaust and Tails
All of this is being put in 96 Velocity 260/280 on a Bravo 1 and a 28 4blade
So if anyone has any cam knowledge that would help me that would be awesome in selecting a camshaft. I plan on pulling my engine at the end of the summer to store it and Im going to build another engine, thats when I plan of getting a custom cam, this one next season will be a back up or a buddy engine.

There’s a million cam threads and 99% come down to either the Crane 741 or 731. Rumor has it that even Teague copied these for his stage 1 and stage 2 kits. If you’re under 9.5:1 and want to keep it easy on the valve train I’d suggest the 731 grind.

Im no engine builder. I just read a lot of internetz.

I believe I should be pretty close to 9.5, from what you have read will the 731 work with a comp 924 spring? I have read through a bunch of the cam threads on here and they are either a bit older and I didnt know if anyone has found a little better combo or my combo is a little different.

Im also open to buying one from here if someone has one they want to sell

You’d have to check your spring height and give Comp Cams a call. Even .015 difference on spring heights makes a significant difference.

Im going to the right springs instead of trying to use mine. Im gonna install the 924s on a l29 for a small cam.

Look for posts by Mild Thunder he has many posts on cams,he is a wealth of knowledge when it comes to cams.

With 9.5:1 that’s a way to go. I went with the Comp Cams 525 EFI clone just to get the 114lsa instead of the 741 112lsa, they are otherwise identical. I’m building 10:1 with aluminum heads 509, and all of my reading showed the RPM air gap to be what I need. At 600hp or less it has gobs more midrange torque without giving up any top end to the Victor Jr.

Is the comp cam really identical to the crane? I was looking for lifters for the crane and came out at $880, for the crane it's only anywhere in the $200s
I don't really know which i should choose.
