MJ Another note, CHEVY HIGH PERFORMANCE MAGAZINE in the july issue built a 505 similar to the one I sell on Ebay. I have alot of people email questions as to why I use production oval port heads, and dual plane intakes on my big blocks. So lets compare my 505 to the CHEVY HIGH PERFORMANCE 505, now let me say one thing, I like the articles that Henry D writes, most readers do, Now lets compare the CHEVY HIGH PERFORMANCE/JMS 505: 10.5 compression, rectangle port production heads, solid lifter cam 259@.050, 1.75 rocker arm intake side, Victor Jr 454-R single plane intake, 850 Demon carb. 622 HP @ 6100 RPM, 594 pounds of torque @ 4700 RPM. Now lets look at my 505 I sell on Ebay: 10.1 copression, ported production oval port heads, 244@.050 street roller cam, 1.7 rocker arm, Weiand stealth dual plane intake, 950 holley. 650- 660 HP@ 5700 RPM, 686 pounds of torque @ 4300 RPM. This is why I build my engines the way I do. Can you imagine what an extra 70 pounds of torque will do for your launch ! Or what it will do for a tight converter, Truly each of my engines are a masterpiece, built and machined in my shop by two highly skilled people who like to drive there cars to track . As for Henry D, you missed the combination, I guess its back to the drawing board, keep writing those great articles, and if you ever want to really do your readers a service, think about doing an article on one my engines, a true value. Thanks to Doug in NJ for running 9.8s with our 505 in your small tire, full body body nova, I need more customers like you!! When you see one of these engines on the dyno make over 670 HP @ 6100 rpms, its truly awesome to see a stock looking big block make this kind of power with a 900 rpm idle, you forget real fast about chinesse aluminum heads and 572 620 hp GM crate engines!
