flathead V8 4x2 intakes
Hi all, I'm trying to find out which, if any of the flathead 4x2 intakes had individual runners as opposed to a plenum.
I did try posting on the HAMB, but little response.
Thanks guys.
Kev

Re: Cold air plenum for carbs
Thanks Ronnie. I didn’t know if 97’s like having air pushed through them, some carbs don’t.
I know there is a possibility of running lean, but with a flatty running out of air high up the Rev...

Cold air plenum for carbs
Hi everyone.
I have a model A roadster with a full hood, running a healthy 293” flathead underneath with 3 97’s on a straight linkage.

Re: 8BA valve seat grinding
I think I’ve sussed it. Just needed to go a bit deeper with the 30 degree first.
One final question, how far do your valves normally sit above the deck height once set?

Re: 8BA valve seat grinding
Hi all, thanks for the replies. As I stated in my original post, I understand that the valve isn’t perpendicular to the deck. I’m also using a cutting tool with a mandrel that fits in both the valve...

8BA valve seat grinding
Hi. I’m in the process of grinding my valve seats to set the lash as I have non adjustable lifters. Due to the fact the valves aren’t at 90 degrees to the deck, my cutting tool is creating a larger...

Re: 8BA Valve length
Hi Gary. Those guides would certainly solve my problem on one bank but not on the other where I need 4.945” length valves.
How much are a set of those lifters Gary?
Thanks

Re: 8BA Valve length
Hi Laurie, that’s what I thought I would need, 0.100” over valves. But on measuring one bank that works fine, the other bank requires 0.040” longer valves?
