Went and had a look at my heads that are part way through rebuild.

Type 186 Later hi-perf or “fuelie” heads, some 186 (‘69 & later) & all 492 have accessory bolt holes; 1.94/1.50 or 2.02/1.60 valves; 64cc chambers.









They cleaned up real nice, new valves etc etc.

Will strip the engine of its accessories, exhaust etc in next few months and get the block pulled and the full engine build can start. :-)

Was in Brisbane last 2 days and got a distant look at a nice early vette.

Not been able to get to much done on mine so this will have to tide me over :-)

Part of a nice personal collection









Lot of other nice cars there as well

I took a few shots today before I start stripping the engine down.

Should have done it earlier in the day as the shadow is not good on some of them.

Getting the transmission Dipstick in and out has always been a pain so I modified the ignition shield.

Using a nibbler then a sanding drum I took about 10mm out of it around the dipstick and blended it back.

CraigH

Had a little time so i thought I would check out the vacuum tank I got last year.



Was meant to be fully restored - Yeah :-)

Seemed to hold vacuum sort of ok but not good enough

So I had a close look at it and noticed there was some bog in a few spots.

Ground it all out and found at least 2 cracks filled with bog rather than welded up.









Dropped it off at my media blaster to get stripped and he will braise up the cracks and we will start again.

Also dropped off the jack to get blasted so i can paint it again.

I was going to paint my garage floor but ended up picking up some anti fatigue flooring from Costco.

Was like playing with Lego - which I enjoy :-)









Less than $160 for what I did

Seems fairly robust, trolley jack did not rip it but if you dragged over it every day I am sure it would, just need to be careful.

Will protect things that get dropped around benches as well.

CraigH

Time to start stripping the engine down ready to get rebuilt :-)

CraigH

Spent an hour this morning and got a bit done ....

- Took off the hood
- Re Routed the Trans Cooler line
- Drained Radiator
- Removed Radiator Hoses
- Flushed heater core
- Removed Thermo Fans
- Removed Radiator

CraigH

Finished stripping it down this morning.

CraigH

Have been testing temperature senders to get one that gives the proper readings for the early C3's.





Needs to be

Temp Ohms
100 220
Mark 109
210 79
Mark 65
250 51

Neither hit the mark.

CraigH

Went to media blaster today and picked up the jack.



Ready for paint

CraigH

New aluminum radiator has a different top and bottom so will need new mount brackets for the fans.

Mocked up bracket out of strip aluminum then will get it bent full width.

Should mount without any screws into the radiator plates.

CraigH

After media blasting the Vacuum tank we found 6 cracks in the tank !!!!!!

The company I got it from said it had been restored...yeah :evil:

They had bogged over every crack !!!!

Well after they are all braised up I should be good.

CraigH

Had the Vette taken out to QIM this morning so the engine can get removed and work can start on the rebuild.

CraigH

Got the Vette back after the engine was removed.

Current heads are 487's if I recall correctly

"‘71-’76 76cc, best large-chamber head; 1.94/1.50 & 2.02/1.60 valves available; latter machined for screw-in studs & guideplates"

Have asked engine builder to do photos for me but we will see how many I get.

When I am not traveling I will pop out to see what its up to and shoot any others that I can.

First step is strip down and clean up etc.

See if its been bored previously.

Then he can order correct Scat stroker crank, pistons etc.

So yes 383 is the route, with only a moderate cam that will be a bit more tame with the extra cubes.

With the 186 heads we will have farly high compression as well.

Terry from QIM is selecting the kit.

I am not building an engine for down the 1/4 mile just nothing too wild, I want it to be reliable and very drivable.

Remember from the outside it must look like a 350/270 down to steel valve covers.

CraigH

To fit the vacuum canister I need to move the Charcoal Canister down to where it should have been.



Most measurements were in the AIM but I needed some i got from asking on the NCRS forum.





Now I have bolt holes that will need to be glassed up.

June 2012

When I painted the frame before I could not get into where the mounts covered it so now i can go back and do that.

Cleaned up and wet sanded the mounts.





Then painted them with a first coat of enamel.
