FOR INTEREST use some of the related calculators here with the specs on your current cam, then compare it to other lobes. Example change the seat duration (advertised duration) and/or lobe separation. See how it effects the effective compression ratio, dynamic compression ratio, cranking compression, etc.

( and yes different cam companies may rate their hydraulic lobes at different tappet lifts, but use their advertised numbers anyway, again for interest only here )

Thanks. Nice to see that someone is actually trying to fix something rather than blathering about with generalities and personal cut downs.

oh, you mean like you do on this thread & others where people are genuinely trying to help you? kind of like how you childishly call people names- does "dough guy" ring a bell?

you accuse others of being trolls yet you continuously bash peoples legitimate suggestions based on facts & far more knowledge & experience than you have. can you say hypocrite??

your tick was fixed by switching to a new cam/lifters... it was not the 2157.

at least a couple cam options were already mentioned. or maybe change the heads to ones that will lower the comp to match that 2157 cam you love. those heads are intended for higher power/race engines with cams of 500+ lift.... not parade cars. no personal cut down intended, just facts & logic.

carry on.
