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

[Waynio]

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.

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.

 

[Waynio]

As oi have ordered the parts i need and waiting in hope they arrive This weeks jobs was finish the lift i have been making.
As i need to make life easier i wanted to get it to a decent height. in this case 85cm to bottom of wheel height.
Hardest faff was getting it to 50cm to get it ot the lift. But my god it works a treat and easy

I have a couple air jacks of 3ton each. made some air lines up to use them independently.

Some folk think i am mental but hey ho. It works nice and easy. I love to make stuff so a project in itself.

So now i have easey access to the wheel arches and can sit on my chair underneath nice and comfy and saved a LOT of money.

I set up the two compressors to run inline for more capacity.

I jacked the rear first and front in sections to get it to the 50cm with a jacking beam, or a length of RHS.

Now to me these are safer than axles stands where some folk think different. But while under a car i would rather this than a axle stands.

So time to crack on with it

 

[Waynio]

So little to show but not been sat on my arse doing nowt. Never do thats why i am soo looking forward to my holiday in a weeks time

For this job i had to lower the car as this is to get the window switches out and door switches also as there a bit sticky.



Found to be a real easy job to do. two screws on side panel/s




then two at the bottom of the console, this had been done before as the screw heads were 10 and 8mm.




Then just Two small screws for the switches then they come out



Then one either side of the front facia



Sorry pics in wrong order but you bet the idea.




So all these are going in the cleaner soon. Just want to strip the carb down once i have.....................






Given it a blast in the cabinet.



After emptying the Allly oxide was cleared, that itself as a faff as i dont want any clogging the carb up. Then i added about 5kg into the cabinet of Bi Carb. After a fettle to the feed set up it worked pritty well, first time i have used Bi Carb in a cabinet, very dusty as expected and difficult to see at time but with the vac connect it cleared in seconds to carry on.

I am in the process ofmaking a propper filer system so i jsut connect the vac diect to the cabinet.

 

[Waynio]

run with these







Oh yes i did this with the Ally Oxide when i first tried the cabinet out the other week.






Carb came up not to bad. could be better but its cleaned up ok. Looks good in the dust hey haha




This weekend ill stick hen in the cleaner, although the lock switches have loosed up nice with a soak in WD40. But ill have split the switch panel from the window switches and ill add then to the cleaner aswell. Its a good size cleaner so i want to not waste the anything.

It looks like the passenger side door panel hasnt been removed much as this is what i found once it was removed. all the other plastic sheet had fell off. in better nick than me and its near as old as me/



i removed the oil pan, dont know why but i did while i was cleaning the block up. AND found it s 4 bolt Then i was told most/all crate Goodwrench engines are 4 bolt. still not a bad thing.





Need a new sump gasket now as the ones i have are single dipstick. No rush though so ill sort one later. Found a couple places to get one from. But i probably get one with the other bits i know ill need in a couple months on my new shopping list.
And last of all i think, i started on polishing up the wheels

comes up ok i reckon.

Thanks but not Industrial just hobby gear really. Inexpensive towards Industrial. Does the job though.

Thanks but not Industrial just hobby gear really. Inexpensive towards Industrial. Does the job though.

Still an impressive set up for hobby gear Waynio and lucky to have it all on your doorstep . But I can`t complain though as my C3 lives in a rental space in a pro racing workshop just a 9 mile drive from home with access to a post lift , lathe and milling machine and compressed air gear . No grit blaster though , must add that to the wish list !

 

[Chuffer]

Forgot the lathe and milling machine !!

What i would give for room like that. I could make it a little bigger but SWMBO wants what bit of whats left of the garden haha. cant grumble. Would not be a great deal more room either for the work to do it. Love my lathe and mill. not used a great deal but as you will agree i reckon, when needed they really are needed.

More rom though means more stuff collected. So end of the day you cant have enough room. Maybe enough for a 4 poster though.
