Yeah, I'm in Idaho not Ohio, so a long trip away... probably not worth the gas. I still have an engine in the car. I am busy with other projects right now so not sure if I will get this new top end swapped this summer or not. I'd like to!

I'm not really trying to make max power, I'm just a bracket racer. It should do pretty well though. I always wanted to have a high riser 427 since I first got into cars/engines during high school... what a long time ago!

I will say the intake is not for any NASCAR engine, not a small block intake. It doesn't fit perfect, but much closer than the Cleveland stuff. It will need a little work, couple different ways to get there. I'll spill the beans later, but... anyone like to try and guess what intake it actually is? It is a 2 piece and has 5 bolts and 4 dowel pins.

Thor, is that intake the Gen II "Thor" intake for the 385 series blue thunder Thor heads? I've set a A460 intake on a FE before... The fit was remarkably close length and width wise ports were close IIRC never pursued it an further than that. Didn't think of how to keep the oil in either. No valve cover rail on that intake. Very neat work you guys are doing. Wish I had more time to play with this engine stuff these days.

Good guess Cody, but no... it isn't a Blue Thunder "Thor" intake. With a name like that I should run one though! LOL. I have set a couple A460 intakes on the HR adapter, it could be made to work but... my feelings are that those intakes are just too big, cross section and plenum. They are designed for 572 and 598CI and 8000RPM, capable of 1200 HP. I don't want "too big" an intake for these heads.

A friend has the BT 2 piece SBF intake for the 4.3 canted valve heads. That one looked better on size, but the ports don't line up worth beans, 2 on, 2 off a little, 2 off quite a bit, and 2 off a ton. Maybe if it were cut into 8 pieces and Marcella welded it back up right... could probably buy a sheetmetal intake for less $$$$.

Any other guesses?

No guess on the intake (actually I do have a guess but I don't want to screw up ::))

You are aware of the reason for B.T. 's using the Thor name for their baddest heads?

No Barry, I actually don't know the answer to that! Please enlighten me.

I wonder why they didn't call the 4.3 the "mini Thor", or Thor Jr.  I have flowed a set of CNC 4.3's with side cant, and they "blew" me away! 443@.800

I'd asked about the Edelbrock Pro-Ports running "production" Edelbrock water
« Reply #35 on: February 03, 2016, 07:47:38 PM »
jacketing or not and don't believe I ever got an answer.   I believe the Pro-Ports must fit inside the confines of the standard Edelbrock external dimensions -- IF this is true then not having to limit intake and exhaust ports to the confines is why the Factory High-Risers valve covers, intake and exhaust ports all sit noticeably higher then production FEs

Barry! Don't tell him unless he gives up the intake manifold info! HAH!

LOL Machoneman! Here are a couple more "teaser" pictures, it gives it away really...




Well, Photbucket is running slow and I can't find the other picture I wanted, maybe I'll post it later.

I think it's an intake for a "goddamned LS". What do I win?

I think the LS intakes a better choice than Cleveland, easier to mount, more selection and ports line up better. That one is for a raised port rather than stock head.

No sir Tom, not an LS. The Chevy bank offset is backwards to a Ford, so our #5 cylinder is toward the front on an LS. None of the LS runners line up worth a damn, well maybe a couple... that and the narrow bore space would require Marcella to weld it back up from 6-8 pieces... something like this. I'm not going there.

It is rather unfortunately that the LS manifolds don't fit (as Thor mentioned the side to side offset is wrong).  There are a large variety of those things available, of course, and I think the bore spacing is closer to the FE than a Cleveland is.  Oh well, Cleveland is still the best option, unless you are talking about tunnel ports.  Then, there is a different, interesting option available...

Now i'm curious about what in heck Thor's could be for and also what else fits a Tunnel Port beside a Pontiac Ram Air V.
 Maybe Nailhead Buick but there aren't any intakes worth adapting for those.

The Ram Air V intake was what I was referring to, Tom  :D

Strange as it may seem (to me :) ) I actually know of only two people who share the name Thor.

You.  And A. T. Francis
