Dangit 200$ set a valve springs I gotta get now.
 






That sounds steep, where did that come from?
 






comp cams recomends two sets of springs for my cam.

One set of doubles for 90$ but they require machining to the heads that will cost more in the long run and a 200$ set of "beehive" springs that don't require machining.
 






my hands still hurt from doing the valve springs in the truck = PITA!! even when the truck has no radiator support, man next time the heads will be on a bench......
 






I'd avoid the beehive springs, if one breaks lots of other parts go with it. Double springs have a slight safety if one breaks. But if you don't go too high in rpm's, then you shouldn't worry about that.
 






Got my parts finally.
 






Well crap now I can't find the part number for the beehive springs.

And I can't find the info that told me the doubles would need machining either.

Maybe I got stuff mixed up.
 






It's okay if you ordered those, they are relatively new on the normal street market. To start with there is the rumor of them failing and the damage after, but that will be race engines, which is far higher rpm. In the rpm range you have, the spring type isn't as important. You do need to choose the springs to match the cam always.
 






Beehive springs have been around for quite a few years.

I would run them, NO PROBLEM in a street/street vehicle. Those vehicles RARELY see the high RPMs in a dedicated race vehicle.

Like ANY single spring application though, high lift, Right RPM, and Long Duration are a good way to break a spring...

just remembered I still need to buy a radiator.
 






Oh hey jaime, what did you do for the transmision cooler lines from the trans to radiator?

Did the a4ld ones line up in the right place?
 






I just bought the 302 lines last Fall, they weren't that bad to get, with the part numbers.
 






Seth

for transmission lines, since I did my first a4ld conversion YEARS ago, are simple


I use a small pipe cutter and cut the factory metal lines, about 8" long, at the trans and at the radiator. Now use a simple flare tool and put a single flare on the ends... use 5/8" high quality rubber trans cooler line with hose clamps, two clamps on each line

no leaks, works great, you can route the rubber lines however you want away from sharp edges and heat

Notice only one hose clamp? well it leaked, so I went back and added another to all 4 hose connections.... that funky thing next to the radiator is my ARB compressor
 






You mean 3/8" right? That's what I used. I used a tubing bender and bent up some 3/8" fuel line with the correct ends to screw into the tranny and only needed rubber hose from the rad (original steel line ends cut) to the new steel lines ending at the pulleys. I second the extra hose clamps. Use fuel line hose clamps and NOT regular ones too. Originally with only one regular hose clamp on each end, I blew a line last year at an intersection and blew red all over a guy crossing the street. Funny thing is, he didn't know where it came from. Light turned green before he could figure it out! I now use two fuel line hose clamps on each end and have run it for a year now with NO issues and that's with no flaring on the steel ends.
 






I am going to use my 4.0L radiator....

yeah me too but mine is leakin like crazy.
 






Matt, thank you for the bolts! Sorry it took me so long to tell you I got them ok, lol.
 






Sweet glad you got em.

Ok i have a problem.

I was just installing my camshaft. When I went to check the endplay both my manuals mentioned removing the camshaft sprocket before checking the endplay.

Except with no sprocket the camshaft can move A whole 1.5 tenths of an inch front and back.

Way over the specified limit of .007".

But when I installed the old sprocket and rechecked and the endplay was right at .005".

So my question is this. Are you supposed to check endplay with the sprocket installed or removed?
