Thread: 396 camshaft

Tweet

i am building a 396 and i have stock heads, and stock lower end, and was wondering what is the biggest cam, i can go with. i will be driving on the street

It's 16 miles from here to the top of South Mountain. Based on this information, how long will it take me to skin a Jackrabbit?

Oh, about this long and so big around------probably needs that rear bearing journal to be notched

In short, we need more information. How much compression? Rectangular port or oval port heads? Closed chamber or open chamber, what year block?

Intended use? HELP US HELP YOU

WHAT PISTONS? IF if you do not use any you can put a big cam in thar but if you run them 2.250 or 2.300 valves them dog gone valves will crash in to the deckthis will fit roller 238/246 @050 621/621 lc112 you should have 10to1 cr that as big as i would go and if a older 396 you will have to dig a ditch in the back cam journal for oil

is dig a ditch the same as notch???

Thursday or Friday looks fine Pat

that cam should fit it i just put that cam in a mild 402 and had piston to valve room with the stock size valves. you will just use a ch 12 durabond cam brearing with no ditch in the cam

hey thanxs for the help

I have 396 motor, and I try to build 396 with most power possible. And I write this because, I would like to clarify many questions.
First, I give the different parts i have for build.

This is the parts i have.
isky cam .63 int- .63 ext
duration 264 int - 264 ext
rpm 3500 to 7500

heads is roller. and the spec heads, is closed oval port with 101cc chamber, valve 2.06 intake and 1.72 exhaust.

bore and stroke is 4.096 x 3.76¨ with dome piston ( .185 more or lest )

The intake manifold is the brodix with holley carburator 850 double pump

MSD 6AL.

But the point is, I like to build the best motor i can with that.

Question; Can i change the piston for other with more dome???

What size is better??

How many HP with this information the 396 can produce?????

How many time In 1/4 mille can produce, with power glide transmition and relation 4.68 with 2500 pounds????

first, sorry for the English.
I hope, I can help with these questions, I hope me understand

Who can help me with the motor??????, I will expect the most HP in the motor.

were do you need the power at? you going just race it or drive it on the steet?here some things i would do rework the heads or buy better .a roller cam solid cam if you taking it up in rpm . you can have any piston made for a 396 .a 454 would help get you more cid if your looking at pistons anyway
