I think a "Blown" 345 would be great. It would sure rock in the mountains!

I know this is an old thread, but I have a whipple on my 01 tahoe. I had to contact whipple once with an issue, and they were absolutely amazing to deal with. I wouldnt want anyone elses sc under my hood. I love it. Towing with my F350 6.0 litre is fine, but I prefer the sound of the SC over the turbo...

Great thead!
Lets be honest... if the kit would fit under a Suburban hood, I will go under the dog house!
A little extra heat can be a prob but a 4 core Alu Radiator and twin electric fans would cover that.
Most of the heat will go out of the Exhaust, so a a good set of headers and a free flow exhaust is needed.
Old post... but did it happen?

Thumbs up Whipple supercharger on 454?

Interesting discussion guys. I can dig the added power the s/c adds, and you will not do damage to the drivetrain etc. if you engage brain and limit use of right front foot. The HEAT will be the biggest problem IMHO. If the doghouse clearance is not enough, when you remake the doghouse, make it Much taller to give more airflow and dissappate heat better would be my suggestion.
Mike

So, what did you decide? If yes, how happy are you with the result?

You could always cut a hole in the doghouse, and have the SC poke up thru... would make a great visual, and with careful sealing I would draw hot air out of the interior and negate the need for a radio too!

Funny seeing this thread I posted here (as Fangthorpe) 7 years later going again. No, I didn't put a Whipple on. I had a couple more gos with their excellent tech guys and they talked me out of it. I don't remember exactly why, but they weren't in favor. I think they were into intercoolers at that point and didn't have one for the 454. The 5.3 ran great without one, but all the later kits had one.

What I DID do was get Ed at EB Racing in Lancaster to build me a monster 454 tow engine that makes more HP and torque than the 502 I was looking at....and runs on regular. He has a chassis dyno that will take a motorhome. You had to be there. I tow the 10,000# race trailer over the Grapevine a couple times a year. Without the trailer the AS is a hotrod, and the fuel consumption doesn't seem to have changed at all. There's a roller cam, ported heads and bigger, higher pressure fuel injectors, headers and a cold air intake. I'm happy with it, but for the cost, I could have tried the Whipple. Maybe next time.
