Harry, don't forget that with the swap i went from 9.4 to 1 with the 6x heads to 11.1 to 1 with the KRE heads. This has given me power all the way through the range. The throttle is as crispor better but I am making a bunch more torque and way more HP with these heads.
I was a bit lean with heavy part throttle and WOT. I switched to a 77 jet from a 75 jet on the primary side. I went to a .037 rod on the secondary from a .043. It is a bit fat on the light cruise with the APT all the way down but it still seems a bit lean heavy throttle and WOT I am around 13.5 to 14 A/F ratio on my Edelbrock monitor.
I did the rocker swap and it has more power above 3000 rpm for sure. I still need to tune and I detonated above 5000 yesterday and seem a bit lean still. Timing is around 30* total. I need to mark my balancer better and check it again. I don't think the MSD is helping much. I need more fuel again since swapping rockers? Plus the air is alot better now. Once next spring and summer comes around ecverything will change again.
I don't think the throttle is as crisp now after the swap. But I am fatter now cruising with the jet swap. And I still need to tune it some more to the new conditions. I think the more lift was wanted by the heads etc. My air cleaner isn't helping me.
I port matched my RPM intake to the 2.3" height and it was at the 1.18 width already. I blended it back over an inch.
I think I need to go to a single plane intake. I run 3.90 gears so a bit of torque loss will have no effect on my combo. I can't get any traction on the street anyway if i try to launch the car.
I attached a copy of the dyno sheets. they are crude. The KRE head one doesn't show much. The dyno was screwibng up. He had to ease the thriottle all the way to 5000 rpm and then punch it from there. The RPMS were jumping all over the place.
The last pulls we didn't bother printing as it was worse. Though on 1 pull it showed the 452 HP peak the lines were squiggly and actually wne tbackwards and in circles,lol.
I am going to try a different dyno for the hell of it but again I have now swapped the rockers. I don't think they made as much difference as I thought they would. But I haven't finished tuning it yet.
