RSCB 5-speed LS1 swap

[zebra]

so this is a while out, but here's what i'm thinking & trying to plan for. any help/input/suggestions are welcomed

i've currently got a 2000 FRC Corvette with a stock LS1 (53kmi) with only headers and a hot air intake (ie: TVS2300). 11psi just ain't as fun as it used to be, so i'm trying to save for a forged 416LS3 to swap my long block out for. that leaves me with an LS1 sitting there begging to be used.

then there's my trusty Penny - the 99 Sierra i did a 4.3 -> 5.3 swap in 3 years ago. i was originally planning a 212/218 cam & headers when i was putting the engine in, but taking 5 months to get the swap done just left me with a bone-stock engine til a couple years ago when i slapped on some headers. that's been fun & all, but it's time for a little more grunt behind the old girl. she managed 275hp/300tq a couple summers ago & i'm looking to up that a bit - especially now that i just went from 265 4-ply tires to 285 8-plies... just feels sluggish (which was to be expected).

what i'm thinking for when i finally can get the engine in the car is to swap the LS1 short block over to the truck with something in the neighborhood of a 220 cam & port my current 5.3 heads. keep the higher compression for quick throttle response (and to make my 93 octane tune more worth it), and a bit of a cam to make better use of an engine swap. i obviously can't go too ridiculous on the cam due to the clutch & 4x4-ness with bigger tires. that's why i picked the 220 neighborhood - pretty mild for a 5.7

how's this sound to y'all who have a bit more experience than i do?

Might run into some mild ptv clearance issues if too much lift is envolved, but not 100% on that one. The 5.3 heads will net some great compression while giving up flow although once ported could even out nicely. Keep the cam mild and port the heads I bet you get some nice budget power going on. Plus the aluminum block ls1 should be what? 80lbs lighter? Not to shabby.

maybe even a 224 - i ain't looked at many dyno graphs yet

I had a "baby" 224 in my LS1 Z28 and it ripped!!!! I rolled up a couple auto MS3 guys on the street I think that cam will be great and also why the hell do you have 8 ply tires on a half ton? Lol anyways good luck any direction you go and keep us dreamers posted!

With properly ported heads and a 220/224 mild lift cam you could easy make north of 350-375rwhp. Are you going to put the tvs2300 back in the corvette with the 416?

'cause none of the 285/75-16 all terrains i liked come in a 6-ply any more

of course
i know of a few companies that make cathedral-port LS3 heads that would be great for it. shooting for 10 to 10.5:1 forged motor on 14-15psi with a little meth for added cooling. should expect a little north of 700 at the wheels - that's the goal, anyway
