Re: Scores From The Race Engine Challenge

There should be a complete final standings order posted here although there is another thread with incorrect information, also. Some of the information within these threads is not correct, other than the winners. I can honestly say, I am boiling inside about this inaccuracy. But, I will let things s...

Are there separate rules for Ford? Sounds like if you showed up with one you’d make whoever wrote those rules head spin.
OR, a Mopar or even an Olds or AMC. ](*,)

Re: Port velocity vs cfm

If this is a race engine and not something driven at part throttle a lot of the time, anytime the air flow requires less duration to make the peak torque number, it will probably go slower if you are forced to use less camshaft than optimum for peak horsepower.

Re: Engine rules?

The EGR intake plenum is actually better than the pre-EGR cast intakes. Being larger does not make it better; especially when the carburetor size is limited. Ask a seasoned NASCAR CUP racer about this. That other MARINE iron manifold, (which would probably be illegal, too), is basically a Performer...

A 60's Q-jet intake with the "R" designation and adapter which puts the carb over the secondary bores. NHRA "stock eliminator" ring pack. A camshaft which is spec'ed for venue for where this engine will run and spend some time finding the best oil pan for power and always keeping the pick-up covered...

Re: Show & Tell Your Engine At The Race Engine Challenge

You need to take this up with Engine Builder magazine; they’re the ones who came up with this idea. They will have a rep at the contest this year so you’ll get a chance to talk about this. Greg ... it is your word here; not theirs. You are the one people are going to point the finger at. So, I woul...

Just for example I will use a 500 hp motor at 6000 rpm. Any Hp there to be gained using floater pins or pressed?

The only gain with floating pins is that you can take them apart a lot easier and faster.

Re: Low speed (1500-1800 RPM) driveability issue

Simply some opinions ... 1. Cam is slightly to big. 2. Wide Open Throttle torque & horsepower mean absolutely nothing at part throttle cruising. 3. Your O2 sensor(s) are merely reading an average ... fuel and air distribution are most important at these RPM levels. When it is reading a little rich y...

Re: Show & Tell Your Engine At The Race Engine Challenge

We have had someone drop out for technical reasons. We thought we would open up that slot for someone who would like to show off their engine. You would not be competing and not bound by the rules; you’re Just going to show and tell your engine. Let’s see what you have - you’ll get some free public...

Wasn’t the -097 Duntov in the FI 283’s like .012”/.018”? They have been around a while
Early slant six Mopars were .008" & .012".

Re: Weird pushrod length SBC?

Gentlemen, thanks for the replies! Lifters are Comp 812's. I just don't understand why with a regular hydraulic lifter that my pushrod is so short? I can see the retro roller stuff being taller needing the shorter pushrod but a conventional lifter? This is where I'm confused. I guess it is what it ...

Re: Weird pushrod length SBC?

I'm far from a professional engine builder so please forgive my ignorance. I'm building a 383 using a late model 350 factory roller, one piece rear seal block with the taller lifter bores. This is a mild street build using an Isky standard base circle hydraulic flat tappet cam and world product S/R...

Re: Gen III Hemi valve spring recommendation

I'll be using the early heads with the shorter valves.. I have three sets...may use the Eagle heads with the longer valves if I do another one of these. Is it possible to use a lighter spring when a Ti valve/retainer is used? Just testing the waters to how this deal will perform. Cheaper to build t...
