Well, my 3X intake is headed to Florida for some work. Should have it back in 5 or6 weeks.

Sorry I was out on vacation for a long weekend. That manifold didn't look too bad, but as has been mentioned I'm going to speculate that when it comes back from 'Florida' it won't have the clover up top and it won't have required any welding. I'm sure it'll be an improvement. I look forward to new results!

Me too😁

Here is a picture of a 440-3 intake, and 440-3X side by side.

And here is a properly ported 3X.....Oh yeah NOT done in Florida

That is what I think a big intake should look like. I've never figured out why Indy doesn't cast them that way. Must be something that Indy thinks the engine wants vs. what the porting guys think the engine wants.

Well I will say that one is on a BIG engine. To be honest I was very impressed with how it came out, both engine and intake. Makes very good power numbers but that's just a dyno number-but for a .500/.488 lobe and under 14-1 it works well. I has been low 7.20's in a 1900lb dragster here in Vegas in the summer.

Al, did you port that one yourself ? Any befor/after power numbers?

Greg, No I did not had a very smart former? board member here do it. I can tell you its runs better than it did with 2x4 set up and on the dyno that was about 40HP but also two different dynos.

Talked to Wilson Manifolds yesterday and i am having a " mid level full port" done. That includes work on full length of the runners but no major cutting I assume. Since there are a lot of changes to the combo, the comparison to the " before" dyno numbers will be hard to figure.
The changes are-
Changed from Milodon gear drive to belt drive.
.240 longer rods
.036/036/3mm rings with lower tension, from .043/.043/3/16 low tension?
Gibtech pistons, L2L coated on skirts same as original pistons.
New wrist pins, DLC COATED .205 wall thick( from .180)
BMP block, aluminum versus iron megablock
Same center weighted Crower crank, which I hope will reduce any issues of distortion and ring seal that may come from a non center weighted crank.
Everything else will remain the same dyno sheet from June 2020

Did you have Jones make you this cam? Did he recommend spring loads? What's the #'s 050 200 LSA? Lobe lift?

Jones spec'd it out. Inverted flank roller, .510 intake lobe .480 ex lobe. 1.7 Jesel Rockers. Duration @ .050 int 284 ex 296 . 113LSA in at 111. .200 numbers are ? 205 int?. Lash is .019 int and .020 ex.

Nice! Did he spec you Seat/Open valve loads?

D
I told him what I was using and as I recall that was deamed ok. Due to economy I stayed with comp 947 triples on exhaust. Set at about 330 lbs on the seat. Intakes I had to go to PAC 1228 due to net lift of .848 after lash. Those ended up at 2.070 as I recall with about 310 lbs on the seat. The 1228 springs have a 2.100 spec installed hieght with 280 pds. At 2.070 they ended up at what I thought was enough since they have less mass than the 947s. The 2.070 is about max for -1 heads and I needed +.100 retainers and +.050 retainers combined with spring cups that are .030 thick.

Got the 3X intake back from Wilson. I wish I knew what I am looking at🧐

Looks like the plenum floor got worked into a shape that will direct fuel into each cylinder in a carb application?

Looks great. Should pick up some power for you. I've tested a lot of Wilson intakes and they are usually 20 to 30 hp better than as cast.

Sounds great to me Andy. I was concerned it may not gain that much due to the methanol port injection, will be interesting when I get it on the dyno.

Port injection?

So I guess it still has to have the fuel rails, etc installed.

Individual nozzles screw into each runner by the head.
