Building a torque monster 308/355

[ricky.chuckles]

Hey guys and gals i need some advice.
I have just acquired a TK Bedford truck. Yeah ok its not a commodore but it has a 308 in it.
Having driven it, the engine is fairly healthy, makes alot of noise but doesn't have a lot of power/torque
The old girl weighs about 3 ton empty and its never going to carry much more than a car.
The engine has to come out so i can restore the old girl, so a rebuild is in store.
As far as i can find out off the previous owner, the engine is a virgin bore turbo pattern block.
So where do i go with this engine? 355 stroker? Turbo? Blown?
I will be building it myself. i want good torque from approx 2000rpm and it wont be revved much higher than 5000rpm.
I was thinking along the lines of either a standard stroke engine or a 355 with good rods and pistons, vn heads, ebay TO4 turbo running 6psi through a blow through carby.
I'm even open to going straight lpg because space for tanks isnt a problem.
Any advice would be great thanks

seems like you already have it sorted, could run e85 if u wana go down that track

wouldn't you be better off with a supercharger if you want the torque right across the entire rpm range ?
I realise trucks use turbos, but diesels are a very different animal to a petrol engine

Cubes = easy torque so definitely go the stroker route.

get yourself some holden to chevy engine mounts and 454 that bitch. you already have the turbo pattern, so itll slot straight in (apart from zorst, but worry bout that later)

Strokers are not as reliable as a standard bore. I'd stay with the 308 engine and give it a rebuild with some light head work and a small torquey cam like a crow 602, small 4 barrel Holley and call it a day. Stay with the old school technology and you can't go wrong.

BBC if you can afford it. If not turbo the sucker

 

[mr j-man]

what about BBW

Ok what is a good turbo cam? Something to spin the snail up nice and early

You need to match the turbo to suit the engine. Doesn't matter what cam you have, if the turbo's not right it won't spool till your revving the nuts off it.
