I went to a Nitto NT05 275 now as that was the closest size they offered that works. I've tried drag radials before and the small amount of increase in traction was outweighed by the cost of having to replace them all the time.
It's pretty cool out here right now which isn't helping the summer tires either. Thread Starter

Just an update. We finally got some beautiful fall weather, sunny and in the 70s, and I got a little street logging in. It is running very rich (before my adjustment) but I spooled it up to 7 grand in 3rd gear a couple of times and it went quickly and smoothly. I know it's just my butt-o-meter but compared to before it is carrying power way up which is encouraging for big numbers. More work to do and I'm still fighting a little idling issues when coming to a stop. The weather is 180* different than last year and let's hope this hangs on a while.

I know it's not an exact science but some of my impression of the heads/cam I get from my VE table fueling. Part of my top end gain is a better valve train but even down lower around peak torque my initial tuning is showing a 10-15% higher fueling rate with these heads from 4,000 rpm on up for the same 12.8 AFR at wide open throttle.

Sweet. That's exciting. I'm pumped to see what power you make also. I did the 383 stroker this past winter and the Mamo 220s are sitting on my spoiler now waiting for me to get some time for install. Probably start next week.

Congrats!! Looks great also under the hood also
How is the idle quality and street manners etc?
Do you have that part of the tune dialed in yet?
Really glad to hear its in the car, running well, and the install is behind you!! (most importantly.....LOL)
Cheers,
Tony

I have to get back into the rocker covers as it seems to have tapping that I think is abnormal. Changing cam and rockers make it a little nosier? To be safe I'm going to recheck the rods. I have Lunati (Morel) high rpm, short travel lifters so the preload is pretty light too. I'v been reading that the block grows about .010 when hot and maybe that has something to do with it. Like I said it pulls up to 7 grand in a heartbeat and I have to be careful in the first three gears going WOT or the back end wants to pass the front.

7000rpm is one thing I can't wait for. My setup now tops out at 6400. The graph was a continuous smooth climb so would be excited to see what happens with a set of these.
Still though congrats on getting it back on the road again at least.
