W5 is a bigger head with more cross section than this new TF head is ever gonna have.
My W5’s were the first set Ryan ever ported. They ultimately went right at 140@ 3220 on super stock springs, so he learned well from Brett.
The trick flow deal with the 418 isnt gonna be a max effort deal. Honestly, i am getting old(62) am awaiting hip replacement surgery this fall, and have zero interest anymore i jumping through the hoops to run 9’s.
Cam wont be big enough to take full advantage of even the flow numbers trick flow claims. Probably something around 640 gross lift before lash/ deflection. Might not even run a roller even though the shortblock is tubed and set up to do so.
I have Harland Sharp rocker gear and that stuff wont clear more than a 1.50 OD spring. Looking around, i couldnt find anybody that made such a roller spring( 1.50 or smaller) Then at Norwalk Vic Bloomer told me such a spring exists that is 1.46 OD. If so, maybe i will go roller, have to get that part number from Vic.
Car wont get any lighter than what it is( 3280 ish with my 320) so of i can run 10.20-30’s i will be plenty happy. Probably need bigger header tubes than the dinky ones i have, and a nice Victor.
Its a zero deck flattop shortblock, so it should have plenty of squeeze to thump pretty good.
Those TF heads are only 60cc
