Once again a bogus combination

Greg Hill · 04-15-2010, 09:31 AM

Examining these crate motor combinations is really eye opening. I did a little research on the 352 Ford crate motor that is in the guide at 285 hp. I compared it to a crate motor that Ford racing sells to the public that is 347 cubic inches and is rated at 450hp.

1. They both have the same heads M-6049=Z304DA. I couldn't find the runner volumes for these heads in the NHRA specs but I would bet they are substantial.

2. The compression ratio on the 352 is 11.25 to 1, the 347 is 9.7 to 1.

3. The cam in the 352 is a solid roller with .575/.575 lift. The one in the 347 is a hydraulic roller with .580/.602 lift.

4. The valve size on the 352 is 2.08/ 1.60. The valve size on the 347 is 2.02/1.60.

5. The throttle body on the 352 is 1000 cfm. The 347 is rated with a 650 Holley that is not included in the package.

Look at the specs. How can the 352 be at 285 if the 347 is less potent and is rated at 450. This is what NHRA and Ford are doing. The 352 is 165 hp less with weaker specs.

Wake up folks. These crate motor cars can run anywhere from AA to M.

Oh and one other thing the runner volumes I just found on Ford racing's own site are 204 cc's on the intake and 85 on the exhaust.

Wake up to what? Its no secret. Just like the LT1-LS1 days. It'll all work out it just takes longer with shoe polish.

We will all be dead and gone by the time these things are correct.

Im with you on this. The older cars and racers (stock and S/S) are "Dead" and dont even know it yet.

After reading the specs. per Greg, it's obvious that Ford surely has a master plan....$$$. Win on Sunday (by using bogus HP factors to spank the competition) and sell on Monday. The sad thing is that the majority of the "fans in the stands" are gullible enough to believe that what they see on the track is what they get at the dealer.
