Can anyone help me identify these small block rocker arms? The are unmarked, un-bushed, and have ball style adjusters. They came with steel spacers too. Are they older versions of the Comp rockers?

Does one make or sell a single v-groove pulley set for a small block that overdrives the water pump? I've seen a serpentine setup from CVF that overdrives the water pump, but can't seem to find one that's a single v-groove.

How do you guys clean the carbon off of the top of pistons and clean the block deck surface on an assembled used shortblock? Is a wire wheel or scotch bright roloc too aggresive?

Will stock 318/360 rocker arms work with Comp 901 springs or 340 replacement springs, or will there be interference issues? Thank you guys.

Does anyone make a solid roller lifter that can be used with stock roller block dog bones and retainer? Or are they all retro-fit with link bars???

Can anyone ID this cam for me? It's an old SB Mopar purpleshaft, but with my mic, I'm getting numbers between a couple. Do these numbers mean anything?

Is there a rule of thumb for how much valve spring pressure stock pushrods can handle? I'm assuming probably not much. How much camshaft have you successfully run stock pushrods with?

I’m getting ready to build a 408 and am trying to identify what cam to use. The block is a 91 360LA block w/ provisions for roller lifters, so I’ll likely stick to a hydraulic roller cam. Here are the specs for the engine: 408 ci (9.7:1 SCR) Indy X/RHS heads (flow 271 cfm @.550 int, 195 cfm...

I have a stock roller camshaft from a roller cam LA 360 that seems to have a long snout even though it didn't come with a pump eccentric. Why did they do this? Can a long snout cam be used in a magnum engine?

Does anyone know anything about '329' 360 heads? I pulled some off a '91 360 and am having trouble finding any info about them.

How do you guys like the Scat 408 cast crank rotating assemblies? I'm thinking of throwing together a "semi-budget" 408 shortblock and have begun pricing out kits. Are the Scat cast crank kits with Icon 745 pistons worth a crap? $1,500 for a balanced rotating assembly seems pretty...

1) Do roller lifters from a 5.9 magnum work on a roller cam LA360 block? 2)Are 5.2 mag lifters the same as 5.9 mag lifters? 3) What is the maximum cam lobe lift before the oil grooves on the roller lifters become uncovered by the lifter bores on a roller LA360? Will 0.375" lobe lift uncover...

1) I've read that some early 5.9 magnum blocks have oil holes for shaft oiling through the head (even though they're not used). What year blocks still have this provision? 2) Do performance replacement magnum roller cams have oiling holes drilled in the appropriate journals to allow for...

Would a LA360 from a 1990 Ram be the roller cam variety? Are there any other differences in the roller cam LA vs a non-roller cam LA besides of course, the roller camshaft? Thanks.

Does anyone know offhand if it's possible to remove a hydraulic lifter in a 340 w/ RHS heads without removing the intake manifold?

Is this timing cover bolt hole blind? Or does it go into a water jacket or the crank case? I was helping my dad put his 360 together over the weekend and forgot to put sealer on this bolt. I'm wondering if I'll need to have him take the water pump off to reinstall that bolt with sealer to...

I warmed up my 340 Dart earlier this morning and started driving it down the street. It fired up like normal and was running great. A couple lights down the street, it suddenly dropped rpm and tried to die. I was able to nurse it over to the side of the road and nothing was out of place...

I was going through some specs in a FSM for 73 plymouth and came across this spec for "dry lash." Since this spec is for hydraulic lifter applications, is this simply the preload range of factory lifters, or something else? In other words, what does this "dry lash" spec refer to?

My dad and I are putting a mild 360 together for his D100 and need a set of pushrods. Since the heads and block have been decked and a number of other things have been changed, I'd like to measure for pushrods to see if the stockers will work or not. Do you guys happen to know what the stock...

What do you guys recommend for a camshaft lube that will actually stick to the cam and not run off like the stuff Comp supplies with their cams? The engine may sit a while before it's fired. Thanks

Can you guys recommend a decent stock replacement hydraulic lifter for a stock-ish 360? Are sealed power any good? Any to stay away from? Thanks.

Do you folks know of a good over the counter ZDDP oil additive that is likely to be on the shelf at a local auto parts store?

Regarding duration at .050" lift, is that .050" valve lift or .050" lobe lift?

I've heard there have been some quality issues with hydraulic flat tappet Comp lifters lately. If that's the case, whose lifters do you folks run on mild HFT cams? Would running a stock replacement Speed Pro lifter be a no-no on a mild Comp camshaft?

Am I reading my FSM correct? I'd like to know the specs on allowable oil clearance for main bearings on an LA 360. Under the crankshaft engine specs section, the '73 says: Diametral Clearance Desired: 0.0005"-0.002" and Diametral Clearance Allowed: 0.0025". I've never heard it referred to...

My dad and I are putting together a low buck 360LA for his D100. When he went to check the Comp retainers and locks I picked up for his new valve springs, he noticed the new locks are much shorter and don't go around the valve stems as far as the stockers did. Why is this and will it cause an...

I need bearings for a stock 360 build. I notice Clevite has H-series, P-series full groove, P-series half groove, and A-series Aluminum main bearings. Which ones should I get? In the past, I just get the direct replacement full groove P-series (MS1266P), but what do you folks think? As I...

I'm having a brain fart. Would a '71 truck 318 be internally or externally balanced?

Any idea what 'LA' hydraulic flat tappet purple shaft cam this is based on the numbers. I don't have a spare block laying around to check it.

In a stock rebuild, is it worth it to go with Moly rings? What are the differences moly vs cast? My dad's putting together a stock 360 LA. His machinist recommends cast rings and I understand moly rings require a different surface finish. I've had good luck with moly rings in the past. What...
