Push rod length tool will be here in a few days so I cam get the right pushrods ordered. I also ordered a 102mm TB and a catch can ...and I picked up a Fast 102 for stupid stupid cheap. Fast is going to get port matched by Shawn this weekend! Guy dropped a valve and there was piston all in the intake. Quick trip to the car wash and shes good as new. These things are fun to take apart when theres metal and oil everywhere !
I have a set of mid length runners if you want to try them lol it will give you a few hundred rpm.....

I might be interested . Not sure if this cam will rev high enough to make use of them properly. Need to dyno this combo and see what the graph looks like

Its not always about where a cam makes peak power, but where the shift falls. Almost always makes a car faster revving it out a bit past peak power if that makes it fall into a meatier part of the powerband in the next gear.
Especially true with a 6L80 you want to rev it out to take advantage of that big first gear, because then it falls on its face on the 1-2 shift with an almost 3000RPM drop.
Sorry if I missed it, but is this going to get a converter with those heads? Definitely don't do the mid-length runners without the converter swap.
Real curious to see what this does - The stock ls3 heads especially with your valve job can make well over 600hp. I don't believe they were costing you anything.
The new heads are much bigger and the rest of the build is real mild. Where/what are you expecting to gain by putting the bigger heads on?

Curious where peak tq is to spec converter and target ideal shift fall back.

I have a 245mm circle D single disc converter on order . For it .

I understand this . This is why most of my builds go faster than the average Joe blow shitty heads cam setups lol still if the cam wont make power up high and falls hard on its face . The mid runners wont help much. Only time will tell. Gotta see where it makes Powa.
Its really amazing how a cam grows with runner length selection. Take the SS4 I had. With mid length runners it would make peak power at 6600 and would carry out to 7600 pretty flat changed to the x1 and that peak moved to 7200 and would carry flat to 8200.

True, I have the summit ghost cam with a super vic and 4 barrel throttle body, revs as far as I let it.
You know, after a long hard day of developing killer parts....looking through MAVN's threads is like icing on the cake. Thank you folks for the insights.

This is good insite. If you want to PM me for the mid runners I'm interested for sure . Have something in the works with @Summitracing so those mid runners will be helpful in the future, even if the little ghost cam doesnt like them

Thanks Appreciate it ! Hopefully this combo will work as good as I think it will
converter wasn't locked for the final numbers, but with the original converter still in place I ended up locking it and there was a difference of 6whp. I left it unlocked as it just bogs the car too much.
