Good day eh! Just new on the board so bare with me . The kids have two projects on the go. Jeff has a 84 school bus with a 366 ( very good rebuilt) he is making into a camper ,this has a 5 speed stick . Will the headers off a car block bolt on ok ? Would a 800 Q-jet give him any better fuel economy , i know that's a stupid question but i was thinking maybe with the smaller primairys it might or does the engine need that honking big holley just to make it go? Tim the other kid has a jet boat with a blown(boom) 460 & we found a 427 td out of a old 70's gravel truck which he wants to put in the boat . He has already ordered alum. heads & intake for it . After all this i was curious what the stock hp & torque would be for these engines . I tried the data bases but couldn't find any thing.Any help would be great. So there it is , have a good day ! Later Bake

The headers will bolt up just fine, but because the heads are on a block w/0.400" taller decks, the turn-down for the collector will be that much higher. If there's room for this to not be a problem in the bus, it'll work.

A Q-jet would be a fine carb for this app.

What size is the Holley on it now? External appearances are deceiving; one of the biggest (externally speaking) Holley carbs there is, is a spread bore 650 CFM.

Get the list number from the choke tower and se what size it really is, if you don't already know.

I actually have one of those waiting for a gasket kit. They are a big honken nasty lookin carb. Built correctly they function just as well as a quadrajet- but the building correctly part is a bit trickier as there is little info on them, so a quadra jet may be a better option if you need a rebuild.

On a school bus with a gas engine you're not going to get good mileage. If you're at all concerned about mileage I'd sell that project now.

One thing that often gets fouled up, is the wrong bowl/block gaskets get used. This will cause the acc. pump to not work, among other things.

They also have pull-over type squirters, most guys don't have a lot of those around for tuning if they're needed.

But yeah. They look bad. And weigh a TON!

I've got one down in FL that was used in my shop as 'decoration', atop an old Al intake. Need to make a trip and get the rest of my things from down there- but I just HATE that 12 hr. round trip...

Thats some pretty wild stuff u got there , it makes my BBB look kind of mellow . Any way do any of u guys know the stock hp & torque of these motors or where i could look it up? many thanks . Later bake
