comp cams part # 1330-16 ?

will part # 1330-16 from com cams work on a bbf a460 head motor? they are 1.7 that why i asked

logan

Sure they will 'work' . Just be down on lift/power a little .

They are listed for use with max diameter valve springs of 1.500. I've not seen any A460 heads with springs that small.

David , is this from a retailers site ? The Comp catalog does not address the spring dia .

That is what's listed on them from Summit's site:
http://www.summitracing.com/parts/CCA-1330-16/

That may or may not be correct though. We know the Crower SS rockers will work with the TFS A460 springs at 1.640, even though Crower lists a 1.56" as max diameter.

BTW Lem, went to the last race of the year for me yesterday. 6 passes. All 4.69-4.70. Best 60' of 1.025

Damn Boy Uncle Charlie is proud of you You should be happy, great 60' times and VERY consistent You can win big money races with that. I know the car is an American Racears swing-arm deal, and they are kinda' heavy, so how much does it weigh with you in it? Around 2150 or so?

the less ratio (1.70)rockers will give up .010" to .020" lift(approx, depends on lobe lift) can still keep total duration by tighten up the lash
