I'm in the process of doing this to my boss's '90 SS454 p/u ...... 496 with dyno'd 505 HP with a 700R4 behind it.
Engine came from Patriot Performance in Ala. Trans is from Monster Trans in Fl. As soon as it's all bottoned up ..... I'll u tube it when it finished. I plan on using ALL of the 454 accesories.

I was originally going to utilize a 502/502 delux carb'd unit but after the dealer (chev.) couldn't deliver one (I gave them 45 days for what they said would be 3-5 days even with paying it in full up front) I went with the Patriot unit. Basically it's the same bar the little stroke it has.

That's it for right now.
