Opinions on this HR Comp cam & Head for my 400 sbc
I have an opportunity to buy a slightly used set of AFR 1054 210cc heads, Custom Harland Sharp 1.6 roller Rockers (offset for head geometry)& Custom Grind Comp cams Part# 12-000-9 CS 3316s/3317s cam HR110+4 for my 400 SBC. I think the price is fair "if" this combination will work with my car & goals.
I have a 65 SS, roughly 3500 lbs w/me in it, TH350 with 3.55 or 200r4 with 4.11, 3200 stall, 11.5 to 1 compression (I will probably need to cut pistons or swap with these heads as 65cc vs. 75cc) that I'm currently reassembling & will be setup with a full SC&C/AFX suspension. This car will see a lot of highway/cruising use, some autocross & road race, and maybe the drag strip a few times a year. It's essentially a toy for me to have fun with my kids on the weekend & race when I have an opportunity.
I have been communicating with CSTRAUB on a package for my motor (AFR 195's w/custom cam) but this package would save me a ton of cash & I need all the $ I can get to finish this by next spring.
Any thoughts or suggestions how the AFR 210's & custom cam would work with my setup? I know I might lose a little low end response with the 210's vs. the 195's but is it worth the gamble? Any thoughts on the power band for this combination on a 400 sbc?
I don't want to waste my money if this is the wrong combination for my vehicle even if it means spending more money to get the right combination the first time.
Here's the cam specs off the card, I can't attach the card to this post:
