Cam install - 5.3 into a vette Hey guys, long time lurker first time poster here.
The car: 1984 Corvette, 3.73 gears, auto transmission, 5.3l truck engine install currently in progress.
I am retiring the old crossfire engine and installing the 5.3 truck engine into her. The engine will have an LS1 intake to clear the hood. Next mission is the cam install. The car must remain drivable as I pretty much use it as a daily driver, although I have a beater for rainy days.
A friend of mine suggested that I go with something in the 228-230 duration 590 lift and 114 LSA Area. That should give me a nice cam, some good sound but great drivabilty. He mentioned running the 918 comp springs with it.
After calling comp cams, I was recommended to use 530 to 534 220/224 and 112 lobe separation.
Considering my 3.73 gears, and the fact that I will be installing a torque converter to match that of the gears and the cam, what numbers or cam should work best for this application? I will need to change the push rods, lifters and springs, but will I need to change the rockers as well? Comp cams says I wont have to with their set-up. THANKS!!!
For those interested, this is the resurrection that took place to save my vette... http://www.digitalcorvettes.com/foru...ight=back+dead

The car!
first off..AWESOME car and story, love the wheels. My first car was an 85 vette that i picked up with a blown motor and rebuilt with my dad.
just sold my 95 vette
I miss her heads/cam fun car until it met a median at a decent amount of speed lol
anyways, I think a 230 cam may be a little big for a dd in a 5.3l that would be more suited in the 5.7l you can have a custom cam spec'd for you by a reputable person here on ls1tech, tell them exactly what you want from the car and you will get it. theres a few guys that are very good at it lurking here on ls1 if you look around.
also you wont need to replace the rockers or the lifters( have to remove the heads to do lifters on these engines) it wouldnt hurt to do the lifters but its not necessary at all.

There's also the Futral F4 (226/226) with either a 112 or 114lsa.

228-230 is a little too big for what you want in a 5.3. Comp was pretty close to what I would do. We have a 221/226 .565"/.560" that we use in alot of 5.3s that would fit the bill great for what you are doing. Our old version was actually a 220/224 like they recommended, but the latest testing for revisions left us favoring this grind a little more.

LOL... I most likely WILL replace the lifters. The engine is out of the car now and on a stand, so I might as well while I have it out and apart. Thanks for the tips LS1 Tech Stories

Thank you for the compliments. 65hp over stock is pretty impressive with just a cam! Do you happen to have a video? Just curious as to what kind of idle I can expect. Thanks
I think comp did a good job picking the cam. Its just the right size for a 5.3. I will b upping mine to a lunati 221/221 soon should make it plenty strong up top. The cam u went with is gonna b great to listen to lopey idle. U will def know there is a cam in it.
