Re: BBC oil restrictors

I bought a used GM 572 crate motor and changed heads (AFR), cam (solid roller by Jones),lifters (Crower), rocker arms (Crower shaft), oil pump (Titan) and oil pan (Milidon). I ran the motor with the changes I listed with exception to the oil pump and pan with no problems. I then added the Titan pum...

Re: SAM's SB2 At The EMC And The REC

Out of curiosity, how many duplicate pulls do you guys make for each change? When I worked in a corrosion lab, we weighed everything at least three times and a calibration check was performed often. A lab scale is much more accurate / precise then a dyno. Usually 2 for me to verify the change was m...

Re: SAM's SB2 At The EMC And The REC

500,000+ dyno pulls = 27+ pulls per day, 7 days a week, 365 days a year for 50 years. Impressive! Once again you have jumped to conclusions based solely on what you guys do. If you had called me I could have given you a good few references of folks who have been with me during extended dyno session...

Re: predicting cranking compression

What psi is considered ok for 93 octane? 200 psi? Cranking compression is not a predictor of whether detonation is going to happen. A hot build will likely crank a lower PSI than a mild build with less CR. Case in point, my stuff......static compression ratio is 16.5:1....cranking compression is ab...

Re: low buck 454

Pass on the E street cylinder head on this it has a cheaper light duty valve and valve seat. Get the better Performer RPM 290 cc oval head. It is only slightly more money.. Valves and springs are good for the isky 396255 Z55 solid cam. You don't want cheap valve seats on any high perf cylinder head...

Re: Too much oil in sump

I see a lot of responses that do not answer the OP question like usual.

I have seen many times on the dyno, even in good wetsump pans where 1-2qts Les can be 20 HP and give better oil pressure in the pull.

Even at the track I have seen this.

I almost changed to Canfields (2nd gen) years ago because the results were so good...but they went out of business. I think they were 2nd gen 195s if I remember correctly.
I personally loved the canfield heads. Ported they made a bunch of power for a reasonable price.

Re: Modification advice for 331 Ford

At 331 cubic inches, you will be better off with the AFR 165 CNC Renegade heads on the street and occasional drag strip trip. The 185 heads will make more horsepower if you change camshafts and take advantage of the increase in flow above your current camshaft. A good beehive spring, titanium retai...
