Re: duntov 097 camshaft

It's a baby solid lifter cam meant for a 283. In a 327 there would be very little lope. Nice thing about it, the ramps are very gentle and it will rev to the moon with little chance of valve float with very little spring pressure.

Re: duntov 097 camshaft

There are several videos on youtube that will answer the sound question. I think it sounds sweet.

Re: duntov 097 camshaft

there is something about the factory camshafts! they have this sound you done hear with todays cams! i think it might have something to do with the low lift numbers of the old days.

Re: duntov 097 camshaft

Unless you're using factory heads, I wouldn't run an oldschool cam, much better out there, technology has come a long way. If it's relatively stock and you could get it free or for a good price, I'd run it, they sound nice. Oldschool cams generall have a tighter LSA (meaning lower number) which adds to the lope factor.

The only Mustang I'd ever own is a Fender.

Re: duntov 097 camshaft

The "097" cam was used in 327's in '62 and '63 (340hp carbed and 360hp fuelies) in addition to the 2x4 and fuelie 283 applications from '57 through '61. Nice well-behaved street cam, sweet sound of solid lifters, uses plain ordinary Grandma valve springs (#3911068, 90# closed, 190# open). Federal-Mogul/Speed-Pro #CS-113R is an exact blueprint duplicate.

Re: duntov 097 camshaft

being used in the 340hp and 360 vettes is why i asked about this cam. if i remember right alot of the vettes had 3.36 gears. i am upgrading to the 8.5 ten bolt and it has 3.23 gears in it. thought if it would work out ok it be a nice way to have a solid lifter cam and nicer gear to be able to drive it on the hiway. that along with no problems being an easy profile. i was thinking z/28 springs would be a nice up grade. by they way its a 4 speed.

Every Corvette application of the "097" cam with a 4-speed came with a 3.70 axle as standard, with options to 4.11 and 4.56; you could also order 3.08, 3.36, or 3.55, but hardly any of those were sold.

Z/28 springs are also #3911068, same as the springs in Grandma's 307 Powerglide station wagon; there's a lot of misinformation out there.

The 3927142 springs were used with the 3927140 Mechanical - 257/269 - .493/.512 - 112 - Off Road cam, not the factory installed 67 68 69 Z28 cam.

Re: duntov 097 camshaft

ok i learn something everyday! when my dad built the motor in the mid 70s, he ran the z/28 or 30-30 cam. these were the springs he bought for it. he broke one and bought a replacement in 1977... wich i found the box for and the spring inside with a bill of sale! $1.40 ... thats funny! so i always thought original z/28 used the same springs. on a side note when i took the motor apart i found one spring that was not red.. he never installed the new spring...

Re: duntov 097 camshaft

Where's pdq67 when you need him? If you do a search here on member 'pdq67' or Google '097' there is a ton of info on that cam. I miss that guy...
