makes sense; I still have the same truck intake but F body oil pan for clearance. I left the engine stock because every cam out there made more tq and hp above 3500 and lost some below. being a 5000 lb 1960 Caddy I opted to keep the low end power as I will rarely be above 3500

F-2 Speedy 09-15-2022 05:35 PM

If I keep the truck when its done I'll build a 6.2 hot rod but it will probably go through a Mecum auction where they bring good money

compedgemarine 09-15-2022 06:25 PM

yea, some of those are bringing stupid money at auction. my caddy is going to be a mostly daily driver for me. I have a 1970 Olds Cutlass SX convertible that is one of about 730 built. last year one went thru BJ auction for over $100k. I have had it since 1983 and paid $750 for it. who would have guessed.

F-2 Speedy 09-16-2022 01:25 PM

Keeping it all Chevy no 9 inch........installed a new 8.875 posi unit with 3.73 gears and new Richmond axles in the 12 bolt, truck will be light should be fine with the 4L60E trans.

Awesome job!!! Can't wait to see the finished project. I'm getting ready to do a LS swap in my 70 Chevelle. Just received the engine, trans and all of the goodies from GM. LS7 427/570 HP and a 4L75E trans, computers, etc.... . Really excited about this one. It's gonna be cool!

Nothing in my drivetrain is numbers matching, so that made it an easier decision!

Wildman_grafix 09-23-2022 07:36 AM

I love the 70 Chevelle, had one myself in high school. Great looking example of one, love the functioning cowl induction. Did you do one of the GM's connect and cruise packages?

Yes, Was planning on doing the LS3/525HP package, but GM has a 3-4 month backlog. This LS7 will be more fun! :D I don't want to mess with Speedy's thread. Will start my own thread once we get started. This supply chain delay stuff is phucked up!!!

compedgemarine 01-18-2023 09:07 PM

this is just a question as I have dealt with those calipers quite a bit. did you adjust them before putting the arm for the e-brake on? also if this is an automatic make sure you use the e-brake regularly with that setup as they will not self adjust if you dont and the ratchet in them will stick and you wont have rear brakes. if you already know about all that then you are ahead of most who use them. truck looks like it is coming along nice. I finally drove my 60 caddy LS swap. few things left to do but for a stock 5.3 it runs pretty nice.

You can always shave the existing one if you feel like doing the work :D

F-2 Speedy 03-02-2023 09:43 AM

Holy smokes Wally Id rather pull the engines in my boat.........:lolhit:

Knot 4 Me 03-02-2023 10:36 AM

If it wasn't so expensive to switch over I'd go with a Holley carb manifold and Sniper EFI setup.

F-2 Speedy 03-13-2023 06:52 PM

I need some help from the LS folks can I change coil packs to the LS3, 5, 7 on this build will the plug and play with the 5.3 truck wiring harness, all the cool V covers are for these coils

F2, are you on LS1tech forums?
If not might want to join. I'd guess lots of knowledgeable guys over there have been through all the same issues you're at hundreds of times.

Maybe your newbie credentials on there are handicapping you.
Did you even get some derogatory replies telling you to search?

No, that is one of my buddy's customers trucks. They put twin turbo setup on it.... and found the limitations of an aluminum LS block at 1100HP on the dyno. Destroyed it! LOL. It now has an iron LSX block. It's badass!!

My car runs better than I expected! :party-smiley-048::party-smiley-048:

Wildman_grafix 04-09-2023 05:16 PM

OldSchool, love the connect and cruise swap! I had a 70 SS in high school and college.

I never seen one with a bench seat?
