Did you get those on the motor or chassis? On the chassis dyno it was 305HP & 480 Torque. The runs were to check on the nitrous for setup and ensure it wasn't lean. Also discovered the C6 was cooked when I got home. Heading back in the spring to do some more runs and check the nitrous with the new water/methanol system.

Thanks. It's a 3" body lift which helped with clearance issues for the ram air box and nitrous and water/methanol plates. Tires are M/T Baja Claws, 35" X 12.5.

A 351M that is now a 603???? It would need a huge set of spacers for the the block and a crazy stroked crank to reach that. A 460 bored 0.030 is a 466 so a 0.060 over is twice that (472). To get 603 cubic inches out of a 460 you would need a SVO block bored and stroked to the max or start with a tall deck aluminum block.

The HP numbers I got show what turning big wheels chew up, I had 33's the year before and lost 50HP when I dynoed again with 35's.

Have any video of it? Love seeing these trucks!

I can't comment on any other casting but for the 385 series up to 40 over is no problem. Once you get over that a sonic check of wall thickness is good insurance, you can go 80 over and sometimes 120 if you're lucky enough to find a really good casting. 80 over and up would be wise to do a half or full block fill to keep the cylinders stable, again it depends if you're racing or on the street. Lots of variables to simply make a blanket statement.

Unfortunately the scoop on the truck is now out of production. Summit Racing has one close to it in style though.

@a1stooge Believe me, you don't XD 10 MPG is not so fun, but the torque is!

Our 460 bored .60 overto 472 as well gets 425hp and 538 tq no nitrous. in a 79 f250 supercab ya its scares people . Although built for nitrous just not needed in a work truck. What did you dyno at.

[meumacaco]

would have liked to see a fe motor built up in that truck

[speedjunkie66]

@JSRmontcalm oh yeah? what about a 440 w a six pack??

[funkyboy4scar]

@63Rebelman ol even though its "not" a 603 it has well over 750 i know that because of the dyno run up in orlando florida idk what kind of block it is now but its the same block as when i bought the truck back in 1978...so idk then guess ima half to exsplore it soon

[63Rebelman]

@funkyboy4scar a 351m/400 block cannot be bored safely past .040 over. so who ever told you it was a 603 is full of crap. They are very tough motors but why put money into one. building a 351w or 460 would be much smarter and easier to find parts for

[a1stooge]

haha i wish my '76 sounded like that with its 300 I6
