Well new guy building a stroker

You could save about $600 by reusing the stock cam and just adding new lifters. That way you can also reuse the stock valve springs/retainers/locks/timing set. Otherwise you'd need to get the following items in addition to the valve springs/retainers/locks and your choice of CompCams cam:

Im just going to suck it up and replace it all, i figure at almost 200,ooo why not replace the whole valvetrain. Your a great help so far man

Yeah with nearly 200k miles on the original engine replacing the whole valvetrain's probably a good idea. Keep the stock cam as a spare though. You never know when you might need it. I reused my 174k mile old original stock cam when my Crane cam/lifters failed and I've put on another 37k miles since.

Im just going to replace it all, might as well do it once and right.

Can you give me info on ls1 valve swap? Cant find anything on it

And im on the fence between mopars purple cam or comps 239-4

[FlyinRyan]

239-4.....

[99OHXJ]

239-4.....

Thats which one i was leaning towards, i like the specs on it a lot.

Going to pick the comp 239-4 cam and lifter kit up next, just cam and lifters.

Also thinking about going with some harlem sharp rockers too.

Anyone know of good bolt kits for external and were i can get arp head bolts and rod and main bolts?

[CobraMarty]

Is this going in a manual or TCU controlled auto trans?

[99OHXJ]

Auto but i have thought of going to a manual down the road

[SilverXJ]

Get the damper balanced.


just get the ARP rod bolts. No need for main or head ARPs.

Alright will get it balanced.

And id just like to get them all just for security.

[99OHXJ]

Alright i know i seem annoying just trying to do this once and right.

I talked to a machinist and he asked why i would have to balance the balancer, also it has no timing marks when it should so i think i got a defect.

Also anyone have a link for good intake and exhaust vlaves?

Should i go with harlan adjustable or non adjustable rockers.

Also does anyone have a solution on how to figure pushrod length out?

And last for now what lifters should i run? I was thinking the comp ones that match the cam, just not the springs as there too stiff

Because they frequently aren't balanced. Its odd that he needed to ask. Ohh.. is it a Professional Porducts? I had one w/o a mark as well.

Also anyone have a link for good intake and exhaust vlaves?

SSI makes some SS intake valves that will work.

Should i go with harlan adjustable or non adjustable rockers.

Roller rockers have several benefits. The adjustablilty is nice to exactly set your preload.

Also does anyone have a solution on how to figure pushrod length out?

Pushrod checker. Search on here for the Comp Cams number.

And last for now what lifters should i run? I was thinking the comp ones that match the cam, just not the springs as there too stiff

I like Johnson/Hylifts. PN 2011 available directly from them.

[99OHXJ]

Im going to ask summit to see if they have one with marks on it

Also cant find this ssi company. Whys it impossible to find valves for the 4.0?

Cant find the checker, found a new machinist that builds conquest/ starion motors real smart guy. If its cheap im having him build the engine, id rather build a 12valve, not too good with the gas jobs

[99OHXJ]

How do yall like the harlan adjustables?

Still have yet to find lifters.

Still cant find valves. OR seals.

Got the head and intake off, same with my banks header to find it cracked....

Going to start porting the head tomorrow.

All the above info is good stuff!
