First C3 Vette and luvin it :)

[teamzr1]

You should look a what the GM specs are to see if they also had one valve much larger diameter as the other
Blue line 1 put are the same length so easy to see the difference in size

Should measure the valve face, if stock intake is 1.94 and exhaust is 1.5 ?

 

[teamzr1]

Here is GM specs for 1972 C3 small block
Does the kit you're getting what ratio are they, being stock is 1.5.0 maybe go with 1.7 ?

Look at label D for both inlet and exhaust below here for valve face diameter

Yep. Just popped out and measured. IN is 1.942 and EX is 1.502 diameter of.valve heads.

I have yet to choose a cam. Just finding specs of it as it is now.

If buying that set of heads better do it soon as it states only 1 set left in stock

What about pushrods, and rockers ?
New bolts for heads, intake and headers
Also heads, intake, header, and carb gaskets

You have a tool like shows on Jegs to pull out and insert the CAM correctly ?
Or a CAM degree wheel, so knowing if installing CAM straight up, or you're degreeing it ?
Lube to use on CAM when installing

I can see you mean business wanio! Got stuck in there straight away, did you get caught out without the plastic bag over the gearbox tailshaft housing to catch that verrry smellly oil
Looking forward to following this build I will go out to the vette room in a bit and see what comp cam , lifters etc and inlet manifold went on my engine build in the states. . Good work

 

[Mad4slalom]

Just looked at the engine rebuild report, mine was a 4 bolt main block , had a rebore to 356 cu inches, iron heads with 2.02 / 1.94 valves . Flat top pistons giving 9.75/1 compression.
Aluminuum performance inlet manifold , and holley 650 d. Pumper carb.
Comp cams 12/246-3 grind xe274 h -10.
Giving 355-365 hp at 5500rpm and 385 ft pounds of torque at4200rpm. Re worked oil pump . So not too expensive a build but gives a nice street motor.
