Re: Milking the oil

A five gallon bucket and your bilge pump. Run it till warm and start adding the block sealer. If it will seal studs, than sleeves should be no problem. Without taking it apart and having eyes on it. I can only guess sleeves are leaking. It was mentioned to pressure test the block. It's where you sho...

Re: Milking the oil

I would get a new block. Sleeves are what I would suspect. You can also try running it off a bucket up to temp with block sealer. Have done that before for head studs on stock blocks in boats. Just to add you went from closed controlled cooling to open not controlled cooling. The sleeves most likely...

Re: Engine Masters rod ratio test results

Longer rod probably likes later exhaust opening , erlier opening due to dwell time in his testing.
Just want to say thanks to guys Camking Maxrace and Stan for sharing the math.

Re: L29 Vortec 454 on a budget

I currently have a 8.1 with 4:11 gearing. Thier is no comparison stock for stock.
On the 7.4, large oval intake, large oval heads with intake valve up sized and stock size stainless exhaust valve and cam specs most wouldnt believe. They never idled smooth but pulled like a freight train.

The economaster was a great carb for high elevation offroading.

Remember the Holly economizer carb. Haha.
Tested the holly street dominator intake for bbc. It was made to clear a corvette hood.
Only thing worse was a SP2P for sbc.

That saw cut Above the siamese bores will be trouble. I imagine a lot of builders will be welding that up. Not convinced on bore thickness either.

Re: I think we should take a good look at the 445 Thunderjet

Looks good from what can be seen design wise.Not impressed with the dyno results tho for a cam swap and intake at that cid. The heads looked like they were touched also so it kinda makes me more sceptical.
Rumor is GM has another 8 liter gasser coming out and would like to see what that is also.

Re: 4130 chromoly tube

Good you found out the issue.
All the tubing I've used is marked US with all specs on tubing every 3ft. It costs more and won't buy any tube without the marking.

Re: Camshaft help

1300 rpm is alot. Are you sure gears and prop are close to other boats running 7300 rpm? Isn't that like 80hp or more off from everybody else if setups are close?
I'd would be impressed if a legal cam change would bridge that gap. My last v drive cruiser took some power to turn 29s to 6200.
