Re: 76cc sbc head

I have a DCR file/program that calculates everything out so I'm not using any manufacturers specs specifically. I really don't want to run that cam & piston combo for reliabilty & torque..... It's what was already there & I was planning to change it but now I'm considering other options.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

Re: 76cc sbc head

hey man for what its worth i was building a Gen 1 406 and jumped the gun before consulting anybody and bought a set of trick flow 195's with 76cc chambers only too be told by my machinest that it would be a total dawg because those runners would more or less choke the motor. Engine specs were as follows: stock block .30 over kieth black pistons at 10.8-1 comp, comp solid roller .552 int. .564 exh. 24?-25? dur. on a 110, pete jackson gear drive, harland sharp roller rockers. I took his advice and switched to a 350 block bored .40 with kieth black pistons same compression.

As far as heads the AFR are very good pieces. You may want to check out Total Engine Airflow. They take aftermarket and stock heads and rework them. They do killer work.

As of the past few years I have only been running roller cams and probally wont be going back to the flat tappets due to todays oils, and the power to be had by roller cams. There are some really nice roller cams that I can think of right off hand for your combo.

Comp 224/230@.050 276/282 HR the have this cam with a 110LC and a 112LC the 112 is a marine cam, I ran the marine cam in a 413 with 10.5cr, lots of great tourque, fun not real radical, good sounding cam.

If your wanting something radical try running the crower I listed above, the cam is a beast massive tourque, you will be rattling windows and melting tires. I was going to have them grind me this cam but put it on a 113LC, but after gettimng jerked around for an hour on the phone I called Lunati.

I havent ran this cam but was very tempted in my 427, comp cams EFI xtreme h/roller the specs @.050 230/236 on a 114LC and uses 1.6 rockers (this could be considered nice a sleeper cam and because of its LC of 114 would make a very nice cruzeable cam) Check with comp to see if this cam would have any type of lope to it, if it does it probally not much.
