Hi All

You might want to use either a 4L60E 0r 4L80E transmission to get a good overdrive gear with the 3.73 gears you have. Cruising will be SO much nicer with either tranny.

The reason I postponed the 4L80 is mainly budget but it's in the plan for future
Is it normal that it took one week to post picture on this forum, I got a message last week that the moderator have to validate my picture before posting and still have now news yet........
Your post count is still too low, I think, to easily post pictures. You have chosen well on the Holley 302-2 oil pan but you might need the Holley one inch forward bias engine mounts to keep your transmission from hitting the floor hump. Have you taken a look at the thread below here on LS1Tech? It is very informative about your swap.

Thanks Rick for the info about the picture posting and also for this link on the engine mounts
The holley oil pan 302-2 fit really well on my engine and frame

Reason: mispelling
Nice car, that indeed is a lot of tire. Looks good.
I hate to see a 454 get yanked for an LS. Ever think about spending a few grand on the big block? IMHO a big block is 10 times cooler in a muscle car than an LS. And nothing beats the power of one unless your going to go FI on the LS. Even still, a snotty big block is an experience.

I'm going torward the fuel injection/supercharger route, this is why I chose the LS.

I'm seriously considering running a single carb roots on my 68 big block suburban along with an FItech system. I already have an NA Fiotech system at home, just waiting to install. Like every other thing in the world with me the past couple of years. Numbers matching and want more power with changing it tooo tooo much.
Hi
Here some picture of my build, those are when I got my LY6 from the donor Savana van Freshly removed form the 2012 Van Freshly removed form the 2012 Van OEM intake removed and engine cleaned before paint.
Here the engine block painted, with Fitech Ultimate LS , Holley rocker arm cover, Holley oil pan installed, VVT system removed, new cam and spring installed on stock head
Griffin rad/fan combo and Summit SFI damper just came in
Been looking between that radiator and a few others for my project. What made you choose it over the others? Keep us posted how that one ends up working.
