The 3000RPM thing I was referring to must be outdated info. That's from something I read with Ford's first endeavor into Direct Injection. The systems ran something like 3000PSI to overcome the pressure of air compression AND combustion...and to inject a relatively large amount of fuel in a very sho...

...What's your opinion on flat top pistons? I have a guy telling me that's the way to go. He actually built his motor that way (same car as me). He says the very tiny quench area gives an artificial octane increase due to detonation resistance. He says when an engine gets in the .065-.125 quench ra...

I wish I could help on this one, but this is not an issue I have any kind of experience with or any insight on. So I was hoping Dave would chime in with some thought since I knew this was similar to his setup. I'm sure there's a way to do it, I just don't know what it'd be since I've never had to de...

Yeah, you can't bore an engine without torque plates. Otherwise the bores won't be round once you put the torque to the head bolts. So they have to bore the engine while the head bolt threads and surrounding metal are under stress. But honing isn't about removing metal. In the case of a freshly bore...

...It's definitely not 3 seconds on these cars. Especially not with the bigger twin screw blowers. If I just nail it WOT the temps stay where they are and keep climbing. The whole entire blower and blower cooling system is heat soaked. Hence looking at the Killer Chiller which I hear works wonders ...

...I think the problem is that high IAT2 temps at idle or low cruise heat soak the intake and or sensor because when you get back on the gas or even WOT they don't just suddenly drop. It takes a good 10 minutes plus of highway cruising with good airflow to bring temps back down... That makes perfec...

...1) Will cams drop my dynamic CR even further to where I will loose HP? OR will the increased air flow provided by the cams increase HP even if CR drops. Bare in mind I'm at 27.5 PSI of boost so there's plenty of air to go around the motor can consume it... You may not loose a LOT of HP, but the ...

Last time I tried to post something, the forum server's "quota" for user-uploaded attachments had been met and it was denying me. That's something only Malcolm could solve.

Is there anything specific you've done to the truck to attain that new best?

Just using engineering logic, I'd think OUT on one component would go to IN on the other.

An arrow of flow would've been more useful.

As long as you have the roller components, you can replace the cam with one that is an HO-cam. Then when you wire up the distributor, wire it up to the plugs in 351w/302HO firing order instead of the old non-HO firing order. The catch is if you replace the cam, that's going to also change the comput...

I perfectly understand. Projects have budget boundaries that are immutable. And it's up to you to decide what the best choices to do with the budget are. I just want to offer as much infomration and opinion for you to consider so you can make a more-informed decision about how the budget is best spe...

I have no experience with this on a carbed setup, but on EFI when this happens, it's an indication that the engine is trying to crank lean. The most common issue is people have updated their injectors but didn't update the cranking injector PW function that dictates how much fuel gets injected based...

I wouldn't mess with the FMS or World Heads. The ones in that link are probably a derivative of the GT40 casting, only put into aluminum...thus not that much of an improvement over what you have. A while back, I remember studying the flow test numbers of about a dozen heads done by MM&FF. The FM...

We talked a lot about cams here, and proper cam selection is important. But I feel a need to put into perspective cam selection relative to other things. The vast majority of an engine is in the heads. The absolute best bang-for-the-buck investment in an engine is upgrading the heads even if you do ...
