That camshaft will want somewhere around 14-16 degrees initial at idle. Then another 16-20 degrees mechanical advance by 3,000 rpm for a total (without vacuum advance) of 32-36 degrees. Your approximate 1.66 rotations of the driveshaft would indicate about a 3.23:1 rear gear ratio.

1/4" IPS (iron pipe size)

It has oil pressure now and 402 lb-ft @ 4,500 rpm & 411 HP @ 5,800 rpm.

Yes, I build engines for a living. Jim La Roy La Roy Engines Challis, ID Anyone could install them if they have common automotive knowledge.

Excellent rocker system. I have used them on a 600 HP small block for over a year.

Got all the parts in, new custom camshaft and everything. Going to pick up the block and balanced rotating assembly tomorrow. I'll get to share the results of the rebuild with everyone but the owner, he died 4 days ago. Damn.

Now have another 1970 standard bore 340 block out getting align honed, decked and bored to +.030". There was a standard/standard forged crank setting in the corner with a coat of surface rust that we'll take to .010/.010. Ross forged pistons and Scat rods going in. We'll redo the previously...

Not my engine, customers engine. But I can guarantee, not many miles it that condition. Beautiful, I think we'll run it as is.....................

Too bad this fix won't be that easy.

The relief driver was right, the oil pressure dropped immediately. The bearing material seized the oil pump and broke the hex off the intermediate shaft. Instantly no oil pressure.

So the owner has back surgery and cannot drive or shift the 4-speed for very long. Yet he just has to go for a ride so he enlists a friend to finish driving when he gets tired. The friend is so worried about driving a car as valuable as a T/A he spends most of his time watching gauges as he...

The Comp 995-16 valve springs suggested for that cam requires the heads be machined for those springs.

You might call Todd Marsh and see what he could set you up with. mopartsracing - Sidewinder Cylinder Heads For Big Block Mopar And there is ProMaxx PROMAXX Performance Maxx Series Big Block Mopar Cylinder Heads 9440

Are those the only cylinder heads you will consider?

Really? We have no idea what quality of 440 engine, transmission and installation this "mopar mechanic" will provide. I wouldn't touch that kind of project for under $10,000. Plus a cheap turn key 360 stroker will cost $10,000 in our shop.

Sometimes the cam cores come from the core producer without the fuel pump eccentric having been ground. The cam companies grind the lifter lobes, not the fuel pump eccentric. A couple of years ago I received a custom ground cam with the eccentric not ground. I called the cam company and had them...

For the $2,500 budget they are all going to be the same quality and need to be checked carefully. I would just use the unbalanced 440 Source kit and have the pin fit checked and corrected and the assembly balanced by a good machine shop. More money available? Buy Molnar crank and rods and piece...

You're right. Lacking motivation.

Follow Comp Cams cam break in advice and always, always, time the camshaft with a positive engine stop to get TDC, a dial indicator and a degree wheel. Dot-to-dot and hope it is right is a lazy, cheap way to operate. Jim LaRoy LaRoy Engines
