Everything sounds good to me. Just put in a 4.56 rear gear and you are golden. No worries. car will run great and much easier to drive.

So - Howards Cams has a Lt1 lobe which they spec at 316 adv, 242 @.050 and 144 at .200
.459 lift


I was thinking of having them grind me a smallblock version od the L78/l72 cam

316/316 - 242/242 on a 112

Or go with a 112LSA Lt1 cam 316/336 - 242/254

Or do you think messing with or trying to redesign GM cams is a bad idea?

I like the 140 cams but your never going to get much grunt out of that 302 from light to light. Either throw a set of gears into it like Sam suggested, or maybe go back to a 30/30 grind. The newer 12-673-4 nostalgia cam has the best of both worlds in a solid lifter. Sounds old school and has better bottom end performance out of the hole.

The car I just bought has the Comp 12-107-3 Muscle Car Cam which is a direct replacement for the 3849346 cam and it works really well in the 302. What else are you doing for the Day 2 finish?

Headers, ignition, a dbl pumper instead of the 4053 Holley,
A good free flowing 2.5 exhaust,
A set of torque thrust d or minilites and radials!

Thats it

Sounds great. You'll have to post some pictures of the car when you get it where you want it. I'm going to put a few day II bolt on parts onto mine. Original set of Cragar headers, Lakewood bars, TT Wheels, Wide Oval Radials and maybe a Sun tach.

great info on this thread-
I ran the stock solid LT1 350 cam in my Z/28 in early 80's after rebuilding the 302. Bought it at Chevy dealer that sold the car originally back in '69. I was happy with it.
I've been collecting parts for a vintage themed SBC build, going with 355 short block and picked a Crane copy of the 140 Cam, plus this Isky 505T Solid grind from a recommendation from an experienced old-timer who picked it over the 140. Its a period cam with 254 Duration at .050/108/505 Lift. I was thinking 1.6 roller rockers to bump lift a bit. Haven't tried it yet- but food for thought.
Cheers!

If it's a 69Z it needs to have good cam in it for sure. The old school people know what they sound like you don't want them thinking its not a 302 car! Just my opinion because I love cars with cams.

No need to be to technical. Put the 140 cam in with a set of gears or even the stock cam will do. Small blocks with high rev cams need gears or your defeating your purpose. Have the carb done and the distributor done along with a good exhaust and you will run great. Hopefully you have the forged pistons in that motor too, or your "old school" sound will not be there. Its all about the combo. Good luck!

Ask (67 Nova Boy Dave) what Comp Cams he is using in his 302. That car sounds great!
