I have a 350 block bored +.060 with stock rods and crank
Deck Height is .024 down the hole with KB 193 (12cc Dish) with .016 fel pro gasket im at .040 quench.
Using Vortec heads casting 906 with a little pocket porting done.
Edelbrock performer rpm vortec manifold
Q-Jet Carb rebuilt
The cam i was thinking about was the Voodoo 262 Pt# 60102
The Dilemma I am having is that with flat top pistons my CR is about 10.28:1 and DCR is around 8.3 Which i thought was high even for premium. On the other hand, if i use a 12cc D dish piston my CR is 9.73:1 and DCR is 7.89:1 it would be easier to run the flat tops but i dont want to have to put airplane fuel in it all the time or something. My climate is pretty cold too. i live in north dakota so it rarely gets over 80-90 even on the hottest of days.
The rpm range seems to be about right for my needs.
I am using this in a 1969 C-10 Pickup with th350 trans with stock converter and 3:73 12 bolt posi
If you have any questions for me please reply.
Also, if you think another cam choice which would be better please let me know.
Thank you for your time,
Logan

Never try to fix the cr with a camshaft.
Your 350 will run fine with flat tops and vortec heads on 91/92 octane premium.
I'd use the GM .026" gasket.
Pick the cam to make the torque and power where you need it. (truck application) I would not use anything bigger than what you picked for your truck.

Why is it easier to use the flat tops over the -12cc KB D dished pistons?

I not an expert at anything but do have a few builds under my belt.

Use the 12cc d cups,the 60103 and a little more stall.

Im not trying to fix the CR with the cam. Im just weighing out my options. The falt tops are $80 cheaper and dont have to be back ordered. Why would i want to run a .026 gasket? that would make quench .050? im almost positive .035 to .040 is optimum.

I would second this, definitely go with a looser converter, or you are going to have idle issues.

i had someone on this forum tell me about this software and i am prity much in love with it. go to comp cam and download CamQuest. you input all of your information about your truck and it will give you the best cam grinds to take advantage your setup. tho it it only gives you comp cams but you can just transfer the lift amount and grind angles to different companies. hopefully this helps, it helped me out a lot.
