<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Vortecpro</div><div class="ubbcode-body">Engine 1.

Blue printed .060 over L72 427, 12.2 compression, 242/242 520/520 solid lifter cam, stamped LS-6 rocker arms, stock GM 840 rectangle port heads, 2.190/1.720 valves, factory 163 intake, 4 quart factory oil pan.

Engine 2.

.060 over 427 10.3 compression, 264/264 560/560 solid lifter cam, roller rockers, ported GM oval port 781 heads, 2.190/1.880 valves, Performer RPM air gap intake, 1 inch open spacer, Moroso oil pan.


Both engines will be tested with the same Holley carb, 2 inch headers with mufflers, which one will make more power?

Mark, you and I both know better. We have talked a few times and not sure if these guys realize WHO is posting!! Motor 2 has a very unfair advantage as it was out together by <span style="font-weight: bold">one of the BEST oval port engine builders in North America</span>. I just wish you were close and not over that &quot;imaginary&quot; line called A BOARDER.

What you should have done is post motor 1 against Wilson 496? That would have opened some eyes on these guys.

John (or you would know me as NPS NOVA on our &quot;other&quot; site, lol)
