Re: Work in progress: A460 Ford CNC porting project
Here's a comparison of the 1" x .5" radius fixture compared to the 1.5" x .625 radius fixture. Where there was an big spread in the numbers we ran it a second time to verify: https://hosting.photobucket.com/images/aa150/Sleepercp/(edited)_Flow_fixture_Compare.png?width=960&height...

Re: Work in progress: A460 Ford CNC porting project
A work in Progress- Flow bench revisited to cross check numbers. Tuesday spent sometime back on the SuperFlow 600 to check a few things - Three different intake valves, two different seat cuts and just for the hell of it four different flow fixtures. The baseline flow fixture was the alumi one I ma...

Re: World alu block; removing material for lifter tie-bars.
Yeah, I just wasn’t sure if those fords lifters are inline (which it looks like) and then if the pushrod cups were centered. Also, it looks like the oil passages run to the inside, not out where he is thinking of grinding.

Re: World alu block; removing material for lifter tie-bars.
I am not familiar with Ford stuff so pardon my stupid questions. Are the cups centered in those lifters? Could you flip the lifters by putting the left lifter in the right bore and right in the left, thus having the extended link bar extend to the left in the picture verses the right? Just kicking a...

Re: Tow Truck Engine
If I were in your shoes, and not knowing all the details, I might use the sportsmans. Unless they were ported to be huge I would open up the chamber a little ( enough to lower the compression and use a thicker head gasket. Then use a good flat tappet and lifters and go with it. Those heads take a be...

Re: Vacuum Pumps: Plumbing Arrangement
Ford Elec Vac Pump on the dyno: test https://flic.kr/p/2pChSpQ Test 2: https://flic.kr/p/2pChSiT Ran the Ford electric pump on the dyno. For the 565 it could only pull 1.5-2". To run one on the street you'd certainly need an oil separator, as I killed one on the dyno in just the short time we ...

Re: best timing setup BBC
I have used basic covers over the top of belt drives. Often times on boats where the driver and passenger are literally inches from the belt drive. I don’t want a girls hair to get in it or my kids fingers.

Re: holley 3310 chokeless body recommendations
I will try to remember and look at one I have to see if it has it. I want to say it does, but I will get a pic when I get my hands on it.

Re: Carb recommendation SBC 383
I bought one of the proforma 750 bodies to build for my Son's 377. I've heard these actually flow 840cfm I wouldn't be keen on 840 cfm from 1 11/16 throttle bores, sounds like a tuning challenge. I think it's the same main body quickfuel has used for years? That is probably the dry flow numbers. Of...

Re: holley 3310 chokeless body recommendations
Just did one using this main body. I would recommend it. I have no data other than my friend likes the way it drives and performs in his car. I used the original 3310 settings. You can’t go wrong for a starting point.

Re: Carb recommendation SBC 383
My annular 750 was down 30hp over my 750 with down legs on a 358 spinning 6500 rpm and making 480 HP. We put 40 dyno pulls on that annular trying every e-bleed, air bleed and jet combo. We had it spot on. Then dropped on a down leg and blew it away by 25 HP on the first pull. I was about ready to w...

Re: Carb recommendation SBC 383
One specific annular carb vs. one specific downleg carb on one specific engine? Glad you found what worked best on your combo. Correct, it is just one data point. The OP is talking about a basic combo that is not far off my basic combo. For that reason I shared details found on the dyno that could ...

Re: Carb recommendation SBC 383
6600 was its peak. That’s where it made 480. Just a basic iron headed, hydraulic roller pump gas boat engine.
