Street 360 W/.528" P.S. Cam
DV has parameters around his 128 rule & some of them require widening the LSA.
Somebody needs to tell Richard Holdener that his dyno testing on on LS engines [ about 8-12mths ago ] was wrong. Dyno must have been playing up......
The three LSAs tested [ I believe they were 108, 110, 114 ]; maybe somebody can link the test. The 108 made more power everywhere, with big gains in the low/midrange. Right where you want it for street car.
And the same for 3 identical Isky cams in a 350 Chev, identical except for LSA, 106, 108, 110. Yup the 110 made more peak hp. 3.4 hp to be exact. But it was down 24 ft/lbs through the average to 7000 rpm. Which would you rather have? I would post it but the writing is too small.
Crower must have missed the memo also, because they had street cams in the 70s with 105 LSA; Grind #32202 for a 440 is one of them.
Joe Sherman was quorted as saying he made more power when he tightened the LSA.
And poor old sig Erson didn't get the memo either because he claims tighter LSA ALWAYS makes more mid range. See below
