Im thinking about putting this cam into a 77 350. Will that cam work with the heads or will i have to get something smaller. If it wont work could you guys recommend me some, maybe some from summit.

The motor will be getting a RPM intake, 600 cfm carb, and headers. This motor also has 8.5 compression

THANk YOU

 

Lift at valve: Intake .488 Exhaust .510 ..You will need to upgrade your springs to run this cam.....try to stay under .480 on stock heads.....

 

It's not a very good cam to begin with, and it would be particularly terrible in one of those smogger 70s 350s with no compression.

Get a Comp XE262 instead. No matter what you put in there, replace the valve springs with whatever the cam mfr recommends (which would be Comp 981s with that cam, and the retainers and stuff to go with them). Throw every piece of the stock valve spring system in the trash.

A 600 carb is also too small for the rest of that combo. By the time the motor gets up to enough RPM to where the RPM intake can do its thing, the carb will already be maxed out. So you get less low-RPM torque than you would from a smaller intake, and less high-RPM power than you would from a larger carb. A double negative with no benefits.

Get at least a 650 CFM, referably a 750 CFM, to take advantage of the intake's properties.

If i used the Comp XE262 , how much is the kit and what kinda carb would i have to use. Also how much power would i maybe be making. And what summit cams are good to use.

 

dd2000 sayyyyyssss.

Hey do u think you could send me the port flow data on the heads and any other data to work for DD2000. Im not to sure how to work all the programs yet. Also where the heads just stock heads, and should all the cams be ran at seat to seat rather then .50 .

THANK YOU VERY MUCH FOR THE HELP
MIKE

 

Mike,
I'm pretty new to the program myself..I used the flow # from 882 heads..76cc Stock....
Do you want all my Flow and extra cam files...or just some specific ones?
Let me know, I would be happy to share them.
You know, those heads are really hurting that combo...

 

That cam is way too big for a relitively stock motor with stock smog heads and 8.5:1 cr. get a cam with a .050" duration of
between 204 and 218.

Use "low perf heads" as a choice to model a 77 350 stock head.
They flow about 190/195 cfm @28" at high lift.

Your motor is a prime candidate for a head swap as any thing would be better than the heads you have.

Sure i wouldn't mine to have both flow and extra cams, thank you very much. I have had DD for a while but i could never really get any good numbers because i wasn't to sure about the flow on the heads and if the cams where seat to seat or .050. THANK YOU

What cam would u recommend, i would really like a summit cam just because of the price.
