Don't drag anything even though it says to. Just open click on pic and load.

yes it is... I asked back when if they would be ok, I mean it's not like I cheated out after spending over 30,000 in parts... I would have gotten intakes if I was advised to. Oh well... I got ten now!!


Text me pics of yours

Btw. I must say you got it going on. I've got a lot on my plate so just kinda read through quickly although think it's great want your doing. Sorry if I missed it but is this going to be 8.5:1 builds with future forced induction or going to stay NA and just want to keep comp down. On another note I sent Valako a 2927 SV and he didn't like it and wanted to find something with longer runners. I suggested sniper jr and he didn't care for the cross section and evidently had tried it on a build and was done making power to low. So we left it with going with the brodix hv2001 dom flange. This was for 555/565 NA builds with the promaxx heads tricked out. I just jumped the gun before heads complete cause he plans to raise the floors.

Builds changed to SC so threw all the concerns of intake out the window. I woulda been very close to your position on this as I don't like to dyno to just look for afr', egt's and oil leaks. Funny how builds can be so similar yet result in completely different likes and needs.

Do a little reading btwn this and bck's and it makes my head hurt. Lol. Keep up the good work. I just ordered speedmaster blower intakes. i was a little reluctant at first cause their an 1" higher than most others. Hopefully the SC likes the extra plenum.

I am running this Canton pan.

https://www.cantonracingproducts.com...MP-MARINE-PAN/

I've had her up to 6500 in dyno several times, in full marine trim, with the remote filter, cooler, etc, and oil psi didn't dip even half a psi. 6200 in boat, no oil psi drops. I do however, only have a 4" stroke. fwiw.

Im excited to see what your boat runs too. I like the 30-33' step boats for making a real hot rod.

You're definitely on the right track about RPMs and operating range
Gonna run the low compression until you get bored then boost them?

My 14 qt hardin pan was same way, This Canton -364 should work too, its actually got more features and is supposed to be a step up over the one you have but we all know there is alot of junk out there for sale!
