Too much cam for 5.3??
I have an L33 5.3 with a 750 holley dp carb, and a vic jr, pac dual valve springs and a custom cam from bullet cams...specs..230/234 612/612 108+3, t56 with 3.73's in the back. Motor is currently apart and getting freshened up. Just looking for some opinions on if this cam will be a good suit or if I should go with something different? This is my first build btw just looking for some incite. Thanks!

Do you know the advertised specs for the Bullet cam? Either way it looks good and will be about right for a manual trans, with 16 degrees overlap it will sound the part also.
Definitely DO NOT recommend anything like the above Isky cam that Blue Knight has linked. As much as I respect Isky Cams, that particular cam is way too aggressive off the seat for a typical street motor, and will be a valve-train destroyer soon enough and most likely a pig to drive with a stick shift.

Yeah im following that thread awaiting more results with the bigger carb! definitely thought you blew it up yesterday after reading disaster struck. With you only running .030 valve clearance and its still being together makes me feel better too. I hope to see some number like that at least! or close.

You won't even need to guess what took blue knights motor out if it blows. It doesn't have enough compression to blow up any other way. I'd like to see that thing with milled 243/799's, better springs, pushrods and a flycut. He'll hit 500 + for sure.
I put together a 5.3, 5 speed S10 with a TR224 588 lift that IMHO had a great torque curve and good hp. Really nice street manners. I could see a 230 working with some lope and moving the band up a bit.

I like everything, but if it were mine, I would have some 4.11-4.30 gears in there depending on how tall of a tire. I like that cam that bullet spec'd for you. Your intake piston to valve will be pretty tight, but many guys push it further than that. I would not mill your heads with that cam unless you intend to fly-cut.

More then likely. The dyno guy says he always takes compression over flow. So after he ports his heads they should flow better that stock 799, 243, or 317 heads of course with a compression bump. Or he can save the porting costs and find a set of 799's cheap.

It would be cool to make more for sure, but theres only one way to find out. The only reason im doing this is to beat my dad down the 1/4 ha I think ill have that no problem...well I hope

Fully restored 68 Camaro with a 1971 gm ls7 crate motor, its like a 500+fwp 454, 12.5:1 cr, with the good aluminum heads off his old 427, new 4spd rock crusher trans, 4.10's out back, 12 bolt, eaton posi, c clip eliminators, hooker headers, only problem is it dosent hook at all, all stock suspension wise. But that's what he wanted when he restored was an actual stock Camaro with a 427 then we put the other motor in a couple years ago. Made 408whp and I think 430lb/ft torque on car crafts dyno last year.
Fastest time so far was a 12.09 at 119, that was with 3.55 rear gear. Last fall at muscle car shoot out I ran a 12.14 at like 112 coasting through the traps because I had a good distance on the next guy. Weird thing was he put 4.88's in the back for an unknown reason. Was only running 12.70's, no more gear. Next day it was like 31 degrees colder at 60 degrees outside and that's when I went 12.14 coasting. Broke out by half a sec. Had a dial time of 12.65.
So if I squeeze a high 11 id be happy for now.

My 5.3 has a thunder racing raptr cam that I just got running a few weeks ago. Just ran at our local 1/8 mile and best pass was 7.58 at almost 93 mph. I think it will get down to 720 something after tuning and better launch. Car is a 82 mustang notch weighing somewhere around 3000.
