L78 cam in 396/325

I'm restoring a 67 rs/ss 396 turbo 400 w/a 12 bolt posi 3:31 rear. I would like to use the L78 cam. The motor is std bore w 67 heads ending 802. Has anyone done this or are there any cam guru's that know if this will work with my drivetrain?

Re: L78 cam in 396/325

Tony,
I tried to run the L78 cam in a 325 horse 396 6 or 7 years ago in a 69 camaro I had. The car had a T 400 w/ 3.73 gears & 2200 converter. I always loved the one in my 68 so I thought I would enjoy it in the 69. The car was such a pig that I yanked the cam back out with in 2 weeks and went with a 270 solid from comp cams. What a differance. Just from my personal experiance i wouldn't recomend it. That cam desperatly needs 11-1 compression.

I hope this helps,

Ditto, the old CC 270 Magnum or the Isky 270 Mega even tho there are more modern cams out there!!

Re: L78 cam in 396/325

It will work with the correct valve springs, but I wouldn't choose that grind. Cam technology has advanced tremendously in the past forty years and aside from making noise that is all that that grind is good for in a small displacement BBC.

Dave,

Right, but he's only talking about a 325hp/396 is why we ain't went BIGGER!

You KNOW how we like BIGGER!! "T-t's" included!!!!!!!!!!!!

He, He!!

And a good old CC 280 Magnum will put him right at a schosh under 400 hp w/ headers too!

Re: L78 cam in 396/325

Thanks for the advice and other cams to use, I will probaly not be using headers just stock manifolds. It's an original drive train car I want to keep the stock apperance, but I like the lopey idle. The car will be mostly street but I will take it to the local track a few times a year. The tracks around here are mostly 1/8 mile so w/ the 3:31 I would think I would want most of the torque and hp on the lower end of the rpm range 5000 and under. Does this sound right?

Thanks, Tony

Yes.

Isky's 264 Mega might be better in the 1/8th.....

It's 264/214.
