So when using Bobs cam you run basically stock 906 heads and exhaust manifolds? What does he recommend for compression? I really want to give his cam a try. I need to go through my 70 440 6 pack motor and was curious what needs to be done per Bobs recommendations. Thanks

Specs are 497 horse , 520 lb ft torque
On dyno last summer in 95deg 110 % humid
Room.
5o5 stroker , 1.6 rockers , 20" vacuum
Dyno operator chuckled and told me
400 horse , he can tell by idle.
His hand flew off the throttle when the outboards
Opened.
It REAlly idles like a 318 stationwagon

I recently installed his cam in my car, which is a stock 440 with 800 cfm Edelbrock AVS, repro Accurate Limited exhaust.

My engine builder was initially skeptical of the cam and tried to get me to do not only a different cam, but the typical headers, aluminum intake, holley route. On this particular car, it wasn't what I was going for. So, the only mods to the engine were internal, .020 over, slight bowl work, adjustable rockers and the carb mentioned. I only have around 100 miles on it so far, but the engine builder was pretty impressed with how it pulled. It's a 69 Charger 4spd with 3.54 gears and both the builder and I are way over 200lbs.

Once I get a few more miles on it, and tune on the carb a little more, play with the timing a little, I'll dyno test it and maybe get a 1/4 mile run in at a local track.

Unfortunately, there's no telling when that will be. I just don't get much quality time with the car anymore.

Here's a short video of it idling.

440, stock "6-pack " rods, Ross NHRA legal replacement pistons in .030, 10.75:1, unported 906's w. comp cams #911-16 springs, Mopar performance 4006767 lifters (preload set at 0.010", crane adjustable roller rockers, Bob's cam installed straight up, stock manifolds (with heat crossover flapper removed), 2.5" TTI exhaust with Dynomax Ultraflows, 727 with stock converter and "Hemi" internals plus a good shift kit, 4.10 clutch type SG 8 3/4. Carbs rebuilt by Bill O. with jetting and springs as per Bob K. and Jim S.

the engine is very strong, wish I would have put it on an engine dyno before putting it in the car but there wasn't one locally...oh well, should be on the track this summer and timeslips don't lie.

DPelltier, Awesome video love it. Hope to have the same setup in the R/T. Please post your times when you get to the track. Take care.

Anyone in the upper 12s with a stock 440 on pump gas?

I just order a cam from him.... going to pull the motor in Cindy and make the change. (383 Stroker (438) with everything else stock.) I dyno'd the motor with the cam the engine builder selected and it was good, but it just didn't idle as smooth as I wanted it to. You can come over and hear it / drive it when the new cam is in.

Will come check it out Cody. I have a cam sitting here. Just not sure on which route to build an engine. All the A12 running low 12s are on race fuel.

Broke in the 383 cam I got from Mr. Six pack two days ago on the engine stand and put the motor back in the car today.

Let me back up and say that my engine builder came highly recommended and with everything else on the build he did great, but he had his "connection" cam company custom grid a custom cam for my motor and after 100 miles I knew it had to come out. It just wasn't right and wasn't running good. Spoke with Bob (Mr. Six Pack) and had him send me one of his grinds to see if it was better. Let me tell you I could not be any happier! The car runs fantastically and is really responsive. I'm running stock stuff (stock intake, heads, exhaust manifolds, carb) and the car feels so much stronger with Mr. Six Packs grind compared to the grind my engine builder put in. Plus it idles and runs so much better.

I would STRONGLY recommend Bob (Mr. Six Pack) to anyone who is looking for a cam grind.

Has anyone used his 340 six pack grind?

I've got one of Bob's cams going into my 383 Road Runner.

It sure is fun watching the Mr. 6Pack powered A12 cars tearing up the 1/4 mile - http://youtu.be/OFaPlDt2jt4

I'll be talking to Bob this week for a cam for the Dart .
