Does anyone have any comments or experience with the Comp Cams Nostalgia Series Purple Plus cams for big blocks? From my understanding, these are massaged factory Chrysler designed profiles for .904 lifters with extended exhaust duration to make it a dual pattern cam, and not Chevy profiles cut...

I just discovered my oil pump housing is leaking on my 69 R/T 440. It's a power steering car, so the oil pump is not the easiest thing to get to. Are there any tips or tricks you might have to do this? Better from the top or the bottom? I do have access to a lift.

I'm going to do a cam swap soon, a .484 lift Comp unit. I already have the recommended 911 valve springs. I want to install these on my stock 906 heads. Should I change the locks and retainers to Comp 10 degree units? Whats the difference between the 741 and 748 part number Comp retainers? Which...

I decided to deviate from stock by upgrading to the following parts. I'd like your input on this combo. The car is a 69 R/T with a Ramcharger hood (hood clearance) 440 Magnum with 4 speed trans and 3.54 gears. The engine pulls about 160-165 psi cranking cylinder pressure with stock 906 heads...

I have Federal-Mogul 350NP flat top pistons which are claimed to be about 9.3-1 with 78cc heads. What's the best and thinnest gasket that's aluminum head compatible to keep my compression at the highest point I can achieve with those pistons? Thanks!

Hey Guys, I've been seeing this subject on here, but did not find the answer I'm looking for. My question is: Will a CH4B intake with a 4150 style carb and Ramcharger air cleaner, have adequate hood clearance on my 69 R/T? Thanks!

Do any of you gents have any first hand experience or opinions on the Nostalgia Plus Purple cam replacement? I was no fan of the original, maybe the new technology and split duration made these better?

I decided to do a cylinder pressure test on my 69 440 just to see what it looks like. The number 5 and number 7 cylinders are pretty low, everything else is between 145 to 155. The number 5 is only 100 psi, and number 7 is 130. I was losing light and I needed to put the car away, so I put it all...

I have a bone stock '69 440 Magnum and I'm considering putting on a pair Of Stealth heads to go with a Comp XE274 cam my buddy gave me. This engine is completely factory stock with iron manifolds, iron intake and Carter AVS and will remain so. My question is, if putting these heads on with all...

I'm looking for new and updated tuning tips for today's gasoline and oils, etc. I have a 1969 Coronet R/T with a bone stock 440 still running the original single point distributor and Carter AVS 4617S carb (both professionally restored). The car starts and runs fine however I feel there's...

I'm running a bone stock 440 in my restored 1969 R/T. The engine and components are equipped just as original. Carter AVS, Chrysler points ignition, Carter stock fuel pump etc. and all fairly new or rebuilt professionally. The problem is that when the air temp is warm, 85 degrees plus, when I...

Hey gang, I'm thinking about dropping a set of 4.10's in my R/T to make it quicker and more fun while keeping it all stock ( it was a factory option afterall). Which brand of ring & pinion would be the best deal for quality, price and reduced noise? Thanks!

Here's one for ya to help me with. The Hemi box A833 in my 69 Coronet pops out of second gear when I'm cruising then mildly accelerate or when i down shift to make a turn. I must keep pressure on the shifter to keep it in gear while making a turn....good thing I have power steering! It's really...
