Hey guys, I'm in the process of building a new street/strip car and I'm trying to figure out what cam to run. So far I've got a 1971 310 block with howards cams retrofit lifters, a tubular GT40 intake, Victor Jr heads, and the motor currently has an e cam in it. I do understand the heads are a little big for a 302 block but I got them for a steal, so I'm just trying to figure out what cam would go with those heads. My pistons already have some pretty decent valve reliefs in them. All input is appreciated, thanks in advance.

I think I'm just gonna settle with the f cam for now, I have another question for you guys, should I port match my gt40 intake to the heads or just switch intakes to say the Vic Jr still or something like that, once again thanks for all your input.
Well when in the planning stages of an engine build you have a vast number things to consider, using formulas and different specs in the process! picking parts and installing them isnt really the way to do it you need to know how the part will affect the other parts and what cartain parts need to work there best!
as for the hyper pistons i ran a 150shot on my last set for 3 yrs and now i have 200 on the set i have now! They are very good pistons i have heard horror stories about then and nitrous but to me i think its nitrous error or missuse that does them in hell you can melt forged pistons too with nitrous just depends on how dumb or stupid you want to get!
Sorry i can really sit here and give and exact map on figuring the write parts set up for what and so forth...
but to figure your vlv sizing to cylinder and this is just a base figure you use your ex vlv should be 40% of the cylinder bore and then the in vlv should be 51% of the cylinder bore! or as close as you can get to your numbers like a 4.030 bore would be 1.625 for ex and 2.055 or so for the intake so you get as close to those sizes as you can but certain cuin will only need so much head and certain heads only come in certain vlv sizes so you have to look at other areas to compensate for an under sized vlv like cam lift and duration etc this may help or it may just confuse you but you get the picture i`m sure!
Hot 302, pop-up pistons, 3/4 race cam, 4 prong race plugs and some go juice lmao! Sig inspired by true ignorant *** people!
I understand that better now, I never knew about The valves being a certain percentage of bore size. This motor is just for a little bit of fun until I get my 351, I was planning on getting all the good stuff now and slapping it on the 351 when I get it. But thank you very much for the information, I'll definitely be sure to use it as a reference for future builds.
