383 build cam question
Ok guys I'm getting ready to do the ole 383 build. I still have this 230/236 112 lsa cam. It has good power in the upper rpm range, but not so in the lower. I like the sound of this cam and the upper rpm power however I'm not going to be doing any racing maybe a trip to the drag strip every now and than. My question is from those with experience should I dump this cam and go with something different or stick with it. Is there a better over all cam that will work good through out the rpm range with a 383?
My lt1 mods we be:
Cam?
Long tubes
52mm tb
30lb injectors
Ported stock heads with larger valves beehive springs
Ported intake
1.6 rockers
3.07 rear stock was 2.59 auto
Custom tune
383 stroker kit
Any thoughts?

if youre going to keep that rearend gear def go smaller
Youll hear a lot of recommendations Id go maybe 8-10 deg smaller be much more driveable and the power will come on earlier
If you geared it more and put more converter to it the 280 would be a hell of a lot of fun.

My hope is that what C409 is saying is correct. The 383 should give me what the 350 wasnt giving on the low end with this cam. The torque convertor Ill be using is a 2200-2500. It sounds like all you guys could be correct to some degree. I might just keep it and see what happens. Im not going to be doing any racing with it so it worth a shot I guess. I was considering dropping the rear down to a 3.54 instead of the 3.07, but this 3.07 feels pretty good with an auto instead of the stock 2.59. Most likely I will have this build on a dyno late this winter. I will share the numbers good or bad.
