Re: Most innovative companies

In the U.S.A. there are very few companies willing to be innovative.
I have witnessed many companies manufacturing an inferior part simply because they make more money from it than if they manufactured the better part.
Innovation is all but gone, unless they can get a guaranty on profit.

Re: How much does moving the cam affect peak rpm?

It happens when the cam is so far off from what's correct, that the change in events is bandaiding the issues. Maybe the exhaust is way too small on duration and/or the Exhaust centerline has the exhaust opening too late, and at higher RPM's the pressure is so high at overlap, the exhaust charge is...

Certainly ... this is only about a 327 cubic inch engine.

Re: overheating question

A question guy: Like many know I own a 79 Corvette. These always had a tendency to easily overheat. Now, I have upgraded the rad in the sense the heaviest core is in it (still copper though) and a Stewart stage 3 pump. Seems to do a fine job when driving even in hot weather, but she climbs easily i...

Re: How much does moving the cam affect peak rpm?

CamKing, you mention the engine will do the opposite and actually enhance upper rpm power when advanced.. is this because of the simple fact that it allows more area/time to fill the cylinder at higher rpm? It happens when the cam is so far off from what's correct, that the change in events is band...

Re: small block mopar intakes

Back in the mid-80's I had a Challenger with a hot 340 that had an LD340 intake and the car ran great up to 7200. I later found a used Strip Dominator for the 340 and it blew that LD-340 away was very surprised by that. The 300-8 Holley was a very good intake ... haven't made it in over 20 years.

Re: 5.3 circle track

706 with 2.00 intake and porting is what I was thinking but to what extent? exhaust is pretty much open and with little restriction. A 2.00" intake valve is a bit large for that 3.780" +.020" bore size. The 1.890" diameter intake valve is not that bad. About 1.940" is the "largest" head diameter in...

Re: 5.3 circle track

What would be the ideal head for the 5.3 in this situation? 3/8 mile dirt track, Likely run a E-85 gas, such as what's available through VP race fuels. Max compression between 9.5:1-9.7:1 The 706 heads have the smallest combustion chamber for the most compression and they flow well, especially port...

Re: small block mopar intakes

curious which intake manifold would be better on a 375/450 horsepower small block mopar, a performer RPM air gap or a old LD 340. the performer has 2" x 1" port, while the ld 340 is 2 1/8 by 1" port plus a bigger cross section. Has anybody done A B A B test or just a dyno test on them? The Professi...
