Default 1984 UK Pro Street C4

I recently had to sell my 1987 C4 project as im moving house and didn't have space for a restoration project. So treated my self to this

















Car was built in 1999 but after completion sat in a speed shop on display till 2014.

The Previous owner bought the car and did a few bits to get it in running order and covered about 1000 miles in it till i bought it 4 days ago.

Has a few small issues namely a small oil leak from the timing cover that will be sorted in two weeks when i move to my new property and get it into my garage.

I have a massive build folder and below is the engine spec/build


4 bolt main L82
Eagle 383 Cast Crank
Hypereutectic Pistons
Claimer +30 rings
Arp headbolts
Brodeix Track 1 Heads
Crower Roller Lifters
Crane Chromoly PushRods
Crane Energizer Roller Rocker Arms
Peter Jackson Timing gears
Hooker Super Competition Headers
Edelbrock 2925 Super Victor Intake manifold
Holly 4150 750 Carb
MSD Pro Billet distributor
Taylor 409 Plug Wires
150hp Nitros (currently disconnected)
Street Scoop
Mcleod 11 inch strip pressure plate
Mcleod Kevlar clutch
Mcleod Steel flywheel
Arp flywheel bolts


Crower 00425 Street Roller Performance Level 4 Camshafts
Comp Cam 12-000-8 Street Roller Cam

Im not sure what cam is in it as i have a receipt for both lol.

The car has never set a 1/4 mile time since it was built but after i get a set MT et rears and sort the oil leak etc i will run it before i look for some more power

I happen to have a guy in the Corvette club that has an 84 with a 502 ci but I have to admit yours has a lot more character in paint. His is a pure drag machine.

I don't know what to say other than thanks for sharing.

Does that rim in the passenger seat really help keep the front end down??

Yep it has a ford 9 inch rear with a spool diff.
The crower cam is the 00425

lol the spare wheel is from my 87 model which i sold.


Even with the cast bottom end and hyper pistons i have done a bit of research and seen that there shouldn't be a problem running a low boost blower or small nitros shot.

Thoughts?

Just don't let it go lean and be conservative with the timing.Would be better to build a forged shortblock and put a huffer on it.

Looks mean and thanks for sharing pics of it.

I was hoping you'd find some keys for the original car, and tell us where you got them. I'm in the UK too, and I'm looking for a spare set for my '93 vert. Hopefully Keith at Eurovettes will be able to help. He's pretty good.

Im currently in the process of fixing the oil leak on the front of the engine as it is currently getting worse and worse.

Most of the front end is stripped apart from the harmonic dampener (need to grab my pullers) as i believe the leak is from the front seal/ timing case cover.

Seeing as i need to drop the sump to change the gasket properly i noticed my sump is in poor condition and seems to have been welded after hitting something back in the day,

So seeing as its coming off anyway i was going to order a replacement. Is a standard 350ci sump going to be ok with the 383 stroker kit thats fitted?

I may order a shallower sump as well to prevent damage later in life and recommendations

That's really a nice car. I bet the painter went cross eyed doing all those rivets. Be a bit careful going over speed bumps. will keep reading this post for those 1/4 mile times.

Currently got the car in pieces swapping out loads of gaskets due to leaks from standing etc. Putting it all back together at the moment which has taken awhile due to to all the parts having to be shipped form the US.

One hurdle i have got is the crank bolt (arp) snapped when undoing.

I need to drill it out and retap it and fit a standard crank bolt as this is the 3rd time an arp bolt has broken on me.

Could someone tell me the thread size and pitch so i can order the correct tap.

cheers
