I guess we all call our big cars (Tank)!
Keeping everything under the stock hood is cool.
My Jason Line (Line Performance) built 440 ran a
M-1 intake, and pushed my 4000 lb. pig or (tank)
to 11.16 at 118. I was thinking real hard about
a tiny shot of juice

Wow, that's impressive performance for a 440 !

I'd like to hear more about your "tank"

something to keep in mind when comparing the 440-2D vs the 337 in this type of build is cost.
the 2D is $350+ before you have the ports opened to MW size, or do any plenum mods.
Indy gets $100 for the CNC MW job, so now you have a $450+ manifold.

on the 2D tested here, i opened the ports to MW size and trimmed down the plenum divider height.
the 337 was run right OOTB(other than grinding down the bottoms of the end rails to clear the attaching bolts of the ICH valley plate), and is only like $229.......if you can find one.
and in all fairness, the port exits on that intake were pretty small for "MW" sized runners, so some gains might be made if the intake were tweeked a bit.
one could probably have that done and still have it cost less than a std port sized 440-2D($350).

Ron can tell you, i was totally a skeptic about the 337 manifold before we started doing some back to back tests.
but for this type of build, its really a pretty good piece.

if these became available again, they would be my #1 choice for the pump gas/street type stroker builds where a MW sized intake would be preferred.

something like the 505 that TonyS built with the CNC stealth heads.
505 dyno thread
take that motor, open the heads to MW size and run the 337 intake, and i think it would be reasonable to expect to see somewhere near a 20-30hp gain, with very little loss of low speed response.

Here's the result ; 15 pushrods that fit perfectly and one that was .120 too long. What do you expect for a $1000 set of Roller lifters these days. These are the Isky EZ-Roll lifters BTW.


Dwayne ordered up a pair so i'll have a spare as well as a few spares of the longer PR's.

So are you saying you have one lifter with the pushrod cup 0.120" higher? Why didn't you have Isky replace it with a matching one so all your pushrods are the same?

---

Yep...that is correct Jim. The cup on one of those lifters is .120 higher in the body.

Unfortunately we found this out while setting the lash and the dyno was booked for later that day. Dwayne fabbed up a correct length ICH cut to fit piece so that we could proceed with the dyno session.

No big deal....i'll just have one pushrod shorter than the rest. I suppose this is just part of the hot rodding game. Guys like Dwayne who build lots of engines deal with this type of stuff constantly...i can only imagine how frustrating this must be.

Of course it's not "right"

not that these things don't happen but for a set of that caliber i'd be expecting a replacement set next day aired at their expense. not that it would necessarily happen but imho that's absolutely what should happen. i've been considering a set of these and this isn't very reassuring. quality control on this set of lifters shouldn't have let that slip.

---

I agree James....the manufacturer should be replacing that lifter but probably won't now that it's been run in the motor. The tight schedule dictated the course of action we took so i'm stuck with it unless i want to replace at my own expense.

This was a first for Dwayne and in all fairness he's never had this happen before with a Comp roller...or any other roller for that matter.

The lesson here is to inspect all parts closely and take nothing for granted. Somebody dropped the ball at Isky

Ron,what brand pushrods are those? Are the cups push-in or one piece? I'm wanting to replace my current ones with better quality heavy duty ones! Randy

---

Randy, those are Smith Brothers 3/8in pushrods....very nice stuff !
