Hey guys,
Picked up a set of 034 bow tie heads.
comp now about 9.8
Im not going to port cause Im gona keep it steetable, and the machine shop did a great valve job I dont wana mess up. They smoothed the combustion chambers is all.
Had a set on a 355shot Chevelle and LOVED them. With the Chevy 140 cam and heavily ported it ran high 11s.

Anyway.... I still have L79 cam, but Im thinkn of going a little bigger now that I can.
Going in the 77 Z with 373 , 4speed.

Any Ideas or proven combos? TOO damb many cams to choose from.

Thanks

proven combination to attain what goal?do you want a 14 second street car? 77 Camaros are a little heavy.are you going to ever use slicks with that 4 spd? any 360 ish HP engine will get you into the 13s if you can hook the car and not break.

Gona run M/T streets when I go to the track. I plan on lightning the car little bit.
Mostly I want to be able to drive it. Had drag cars, I think I want this one to be an all purpose car. Altough I have getting the itch to get back into drags.
I may build Z to resemble a vintage Trans Am car.

I am just getting it running asap. I am going to build a more purpose built combo later on.

Don't worry about the pistons being dished. With 64cc Vortec heads you will have plenty of compression,I'm guessing in the 9.25-9.5:1 area.
Evan with 76cc heads you will have a true 8.4:1 ratio with thin head gaskets as per the many goodwrench build up articles.Which is a little low for the L79 cam but not a total mismatch,with your 3.73 + 4spd setup to make up the bottom end.
My uncle has a dished piston stock short block with the L79 cam and 462 fuelie heads(2.02s though)and that motor is plenty stout and snappy for a cruiser.......and sounds nice too.
