Like I have said there is more of a gain correcting lifter bores on a roller cam then a flat tappet cam.
I totally agree with that, due to the aggressive ramp speed of a roller cam. I would like to go to .904's but can't see wasting the time on a stock block even though i have the equipment and knowledge to do so. I don't know what the HP gain would be by centering the lifter bores. In the 5 different 434" engine between me and my friend Jeff Russell we do have 2 Dart little "M" blks running (all injected alcohol) and donot see a lot of difference in performance, but when re-upping the engines there is more main cap walk with the stock block. all the stock blocks are hard blocked to the bottom of the water pump inlet holes, for better ring seal, which is not necessary to do on the Darts.

What type of equipment do you have for blue print boring the cam tunnels and lifter bore work and what cylinder honing equipment do you guys use?? And the name of your shop.
We use the Jesel .904's as they use a bigger wheel on those lfiters.
let's stop all this argument,
I donot have the speciality equipment that you have to build engines. What i have is the ability to build engines that for the most part last a whole season and perform better than most, Example 1 dragster runs 5.16 with my 377" motor, 1 dragster runs 4.94 with a 434" motor, the very ugly 1963 dodge runs 5.80's with a 434" motor. all of the motors are on 23 degree track 1 heads, no full CNC porting, no nitrous, but alcohol injected. theses are big blk times for a lot of people. 2 of these are stock 2 bolt main blocks, 1 has over 200 runs on it. I am not a professional builder and do not make any money on the engines i build, i only build for friends and myself. I have a video of all these runs and as soon as i can learn to change them from 8MM to cd-r i wil post them for the none believers.
I have nothing to hide and nothing to gain by the statements that i have made.
I know i can build 900 plus HP with 18 degree heads but i haven't been there yet. I'm building a 434" motor with Brodix 10's that i think will have about 850HP, but the video is worth a thousand words, and we will see what happens with the new motor.
Bottom line let's be friends and help one another rather than bash one another, i know you know what you are doing and i only ask respect for what i know and what i am doing.
Your friend
