so its not to late to go 383 then ?

funny you say that, builder did say he had a couple of stroker combo's in the back shed, 366/372 sprintcar
but the pistons were already purchased and block machined :evil:
i karnt go radical because of my historic rego rules :)

finally got the chassis/ a-arms painted, just have the spindle arms to go
this heat we are having the last weeks is killing the progress, been high 30's mid 40's, hotter in the shed, lousy for painting
might even start re-assembly of the wiring/vacuum of a night time if it cools down soon...

MATE that builder should have checked everything and told you what was trash BEFORE letting you buy new bits so you could have made a total plan of the new motor. :evil:

he had already sourced the pistons etc, he was only joking about using the cranks

our lhd cars here in sa have to be stock, as it came from the factory, no modifications :evil:

we are also inspected for club rego every 3yrs, cannot even put extractors on

so a mild rebuild is all i'm going for :)

You could always push that a little River....

Stroker kit, stock double pump heads, early C2 vette rams horns with 2.5" outlets. No one would know but U :-)

I know your doing some of it already but there is always more.... :-)

Still, with the mods you have already got planned it will be a big improvement for sure.

You should not need to cut any vacuum lines.

They need to run down past the radiator support through the indent then to the left and loop up towards the top lip.

They then follow the top lip of the nose like the harness and are held on with loop clips

Looks great.

Wish I had done convertor when I had it out so will be interested in what you find.

Also I note he had the heat riser blockers on the intake gaskets.

I thought re that but it gets cold hers so I wanted the factory choke to work as well as possible.

Seems common though to do it.

thanks all, it's been a long hard slog sometimes, any wonder i got no hair.....
still got a bit to do, but there's light at the end of the tunnel now
will get the interior back in this long weekend, finish painting brackets and rad support frame
if goes to plan, pick engine up tues, fit brackets, pulleys, spark plug wires n shields, fiddly stuff etc during the week
hopefully drop in next weekend, and fire it up one night next week
engine builder is tied up with a drag race meeting next weekend, so will get him here after work.
would rather him take control on fire-up just incase :shock:

:o

here's a bit of bubba's work, removed the torque convertor and look what i find
must have stripped a 5/16" thread on the trans pan, so they poked a 1/4" thru and made a flat nut

Image

think it must have been squeezed up passed the convertor whilst in place

have built up the surrounding area with epoxy metal, will drill and place a helicoil in when i drop the pan to change the filter

Wouldn't it have been easier to just put a helicoil in in the first place?

been keeping low for the last couple weeks, everything was just getting on top of me, so i've pulled myself together and got a few things done on engine

lost my waterpump couldn't find it anywhere, ordered a new one, then found the old unit the same day i got the shipping msg from ebay...:evil:

ign shields over the wires, POR15 coated exhaust manifolds, a/c brackets, ps pump, dreaded fuel pump, all ready to go in
Image

1st attempt at going in, got all the way in and engine mount bolts in, bell housing started to be bolted up,
but then had to lift out again, torque convertor wasn't fitting properly :x-
Image

as it sits now, almost ready to fire up soon
Image

drain plug weld to trans pan, hope it dosent leak....
Image

here's a tip for the radiator and shroud install, bolt the frame, radiator and shroud all together as one unit outside the car,
then install as one unit, bit heavy n bulky, but easy done with 2 people, saves the cursing an swearing trying to get the shroud past the A arms.
took 5min and it was all back in.
then only put the bottom side frame bolts in, then lift top towards the front, slip the bottom radiator hose on and clamp.
lower back down, install the rest of the side frame bolts, done.

well, pulled coil lead, cranked up oil press, it fired first turn of the key, then vroom vroom, except for an exhaust leak...

when i was bolting up the pipes to the manifold, i heard a 'tink' sound,
thought it was just me hitting the pipe/sump with the ratchet, apparently not.... :evil:
Image

now i need to find a #3932461 manifold, with the drilled AIR tube holes, they are used up to '82. hint hint

mechanic took it for a couple laps around the block to bed the rings in, it's got some pep
just need to install hood, then -) time

is nothing beyond the chinese?
this is the temporary exhaust manifold i have acquired...
bolt holes dont line up properly, cannot get socket/spanner on some bolts as the casting is too close :evil:
Image
have found an original in the states for 130$ and got it shipped for 55$, i'm happy with that price...:o

calm b4 the noise
Image

dyno sheet from todays pull, they only took it to 4800 rpm as she's still tight.
just wanted to check the mixtures, air/fuel ratio etc., carby comes off sun night, drop back to them to re-jet
Image
red lines - old motor about 135kw = 181hp (early 2011 was dyno'd, just after i got the car)
blue lines - new motor 192.5 = 260 horses
considering the original only came with 200hp @ flywheel, and at the moment i got 260hp at rear wheel :mad:
they very happy with it and expect just under 400hp when run in
and with cast exh manifolds as well, no extractors :shock:

thanks bfit, but i have already bought one from the USoA, 206$au landed here

"Big City Corvettes" had postage with UPS for 94$us, or if i ship on a mon/tues, they have a 55$us fedex deal, how could i refuse that....

i did ask on here, i emailed George, asked local guys, but none to be found, so found the ebay item.

the borrowed chinese crap will go back to it's previous owner or if he dosent want it, then storage for emergency.
