5.3 swap in OBS Chevy c1500 w/ TR220 cam

[BANDERASM6]

Good swap dro. Like the engine cover check my swap out on my 94

[gearheadhuff]

hey how do you do the wiring on the conversion? I have a 93 1500 and i found a 5.3 for 500.00 with 117,ooo on it out of a 2000 suburban. I'm very mechanicaly, but just not that up to date on wiring. any advice would be greatly appr.

[flattopwill]

@gearheadhuff There's not really a way to put it simply. You just have to pull out your diagrams and dispose one by one the wires you dont need. Then add a fuse block and fuse the the systems that need to be like igntion coils, etc. Then connect your factory systems like ignition switch and fuel system.

[flattopwill]

@gearheadhuff I'm not good with wiring so I got one of my GM tech buddies to do it since hes good with wiring. You can buy one already setup for standalone for ~$450 if you dont want to mess with it.

That truck is gorgeous! Sounds awesome! Great Job!!!

[Hectorson3]

that sounds evil

[lowP0919]

That's a nice setup with a 5 3! I been wanting to do that the same thing to my 98 chevy silverado. You think you can give me a call my # is 9125905865

[jrocha383ws6]

@lowP0919 heyy i need help finding what i need to install a ls engine in my 1998 1500..

[zayres29]

do you think doing a 6.0 swap is worth it over the 5.3 price/power/etc ??

thanks

[flattopwill]

@zayres29 Personally, no. The marginal benefit from a 6.0 over a 5.3 does not outweigh the cost. Ready to fun 5.3s can be found for less than $500 while its hard to find a long block 6.0 for that.

[zayres29]

@flattopwill thanks for the reply i have seen (locally) a 6.0 with trans and harness (not sure if it was 60e or 80e) for as little as 850

[flattopwill]

@zayres29 Thats a good deal. Take it.

[zayres29]

@flattopwill if i can find another at the price or close i will but i will def keep the 5.3 in mind is it basically the same swap for the 2?

[flattopwill]

@zayres29 is what the same?

[zayres29]

@flattopwill swapping the 6.0 and the 5.3 i know they are both ls based but didnt know if they were completely different or not

[flattopwill]

@zayres29 They are the same block (except bore) if thats what youre asking.

[zayres29]

@flattopwill yeah thats what i meant

thanks again

[WillDaBeast696969]

oh my..

[mandrgalvan]

how do you like that RevMax Converter?

[flattopwill]

@mandrgalvan

I dont have any other high stall converter to compare it to but I have had no problems with it.

[N0XI0USB4C]

What did you paint it with? Looks decent satin black !!

Also have a 91 2wd scsb that I'd like to LSX but I've got other projects. Props on the nice work :)

[flattopwill]

@N0XI0USB4C

Its just black primer/sealer

[DylonTheGreat521]

change your air intake setup its robbing you atleast 15hp

I have a 95 chevy swb, that currently has the crummy 4.3 in it and i am looking at doing a swap to a 5.3 like this, or a corvette ls1, how difficult is this to accomplish?, wiring, fuel pump, mounts, etc. any info would be greatly appreciated. The truck sounds nice as hell by the way.

[flattopwill]

@hemnkyjr

All the swap info can be found at the ls1truck.com forum. You have to have a stand alone wiring harness which is made using a modified stock harness. You can modify it yourself or buy one from a swap company. The mounts were easy for me since I was coming from a 5.7l v8. A v6 truck will take some more work. You will need a fuel pump from a 96-98 vortec truck to give the new engine 55psi at the rail. All the details and more can be found at ls1truck.com

VERY Clean

[krboer]

sounds good, How are the ls6 springs holding up to the cam? I have been looking at cams for my 5.3 swapped s10, I already have ls6 springs but just want to make sure I won't have to replace them every 30k miles.

[flattopwill]

@krboer Well I havent put any more than probably 4000 miles on it but everything is holding fine. No problems to report.

[KINGKONG0726]

Nice truck!!

[flattopwill]

All you do is leave those wires in tact when you cut out the old stuff. Then, after the new motor is in you just plug them back in. A/C, gauges, and dash controls arent dependent upon the ECM. For the A/C you have to buy an aftermarket mounting bracket for the compressor.

[bmxman242]

how did you do your wiring harness for your ac and dash controls,gauges

[oldbmxer]

nice. what kind of power? any 1/4 runs?

[j20062006]

that's a nice sound and nice cam.

[flattopwill]

the factory cup mounts with Trans Dapt 4572 adapter plates

[Love2Race79]

what motor mounts did you use?

[flattopwill]

Not at all

[caca956]

nice truck! was it hard to put that engine in that truck?

[Toclcl]

NICE!
