Test for both consistancy and power advantage. I have a small block stroker combo I'm just getting back together and everybody is telling me a domy would work better than the annular race demon 4150 that ran very well on my last setup. The manifold carb adapters vs using the correct manifold could also be tested.

It has been suggested to me by a friend that you guys should p.m. or email ideas to me instead though. I have no problem sharing information,but sometimes things are beyond one persons control. Thanks again Keith

A lot of these ideas( the easy and least expensive) I will work on while I have down time and share on here. Since I started writing articles,the ideas I would need to invest a serious amount of time and money into would probably better be made into articles.. I was informed of some unscrupulous guys running off with some ideas if shared on a public forum. Keith www.dunnuckracing.com

Adjust the throttle to put out 100 HP at say 2000 rpm then see how much fuel is flowing. Most vehicles can maintain a steady speed at 50-100 hp or a lot less even for some more aerodynamic cars or slower speeds. Any how I think 100HP@2000 RPM should be the standard for MPG testing, then gallons per minute consumed will be the measure I am not causing global warming, I am just trying to hold off a impending Ice Age!

Roller cams and valve springs, It would be cool to see the curves from different lobes and centers also advance & retard, for a givin compression moving the duration around ect... We<Moparts people> may be able to ship ya some spare grinds to test

Windage tray vs no tray vs scraper vs lower oil level. Anti reversion plate vs none. Perfect vs crappy piston to head clearence with same comp. E85 vs gas.

Some are relatively easy and inexpensive others would put me into bankruptcy ! I have a little 360 pump gas engine for a mule that I can start with,but the power numbers wont be very impressive for quite a while. Probably build a big block mule soon too.

Would be one of the easiest things to test IMO. Do a dyno-run, change the oil, run again, aso. I agree, would like testing to go a couple of steps farther. Crankcase windage , oil control, affects of synthetic Vs dino on both. Tests to see how much oil stays up in the rotating assemblys, etc.Clear plastic panels in an oil pan for observation on some tests done years ago, but only after researching what has been learned. There is a wealth of knowledge at the engineering departments of the big auto companys and it would be great to have some of that info rather than reinventing the wheel. A look at some of the newer motors like the high rpm, smaller efficient ones coming out in the last couple of years might reveal some clues and give us a better starting point. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

Another test would be valve train tests to see how close a flat tappet can come to a roller with some of the Nascar tricks used on stroker motors. Cost vs power. My first thoughts were titanium valves and 2.0 ratio rockers combined with ceramic lifters. Put these parts on different sized shortblocks with a given head, to find out just how close the power levels can be. First off would be to establish a budget, so there is a definite savings for both building and maintaining a combo. Low rpm strokers might be the most cost effective and most attractive for budget builds. A 541 shortblock with small port wedge heads comes to mind as one test. Rpm would most likely stay at or under 6,000 rpm. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

I think it all in the crank flex. I would love to see someone build a motor with a single plane intake and a standard firing order cam. Then put in a 4/7 swap cam see what the power difference is. Then swap out the SP intake for a individual runner setup like a Hilborn , and run both cams again.

The SB Chevy may like different things than the SB and BB Mopars like I've added oil to a BB after breaking in the motor with 4 quarts in a five quart pan, the dyno operator was shocked that the motor didn't loose HP and torque with 5 quarts versus 4 quarts of the same brand, weight and batch of oil Apples to apples, oranges to oranges in testing Mr.Cab Racing and winning with Mopars since 1964.
