we pulled a very tired blue 202 which had done about 110 000 k,s on lpg out of an 84 WB ute and slotted in a less fkd red 202 along with changing from a 3 speed on the tree to 4 0n the floor.. all work well no knocks no oil leaks and runs ok on the gas just vavle noise... anyhow i want to see what kind of build we can do for this blue motor it's standard bore, (still has GM hone marks.) the head has been replaced twice with a lpg/ unleaded picked up from repco at a rip off price.... the last one lasted only 18 months hence the swap of motors this time...
so any idea,s would be great i was thinking along the lines of lil more power and tourqe.
basicly i can put together anything i just need the parts or the right parts to do so.

C'mon Peter, i would have thought you'd suggest running it on gas with a supercharger!!
My suggestion, get a nice cam from the Crow Cams catalogue and some headwork (along with the usual rebuild stuff). Should go alright! Then get some extractors and

If you get a black VK injected motor you get a (veryclose to) XU1 cam as stock. Except the valve timing is a bit retarded to get better emissions at idle. I don't understand how a motor that has only done 110000 is stuffed. You say the bores still show th

Definitley get a gas cam, they give you nice smooth torque. That combined with the extra torque of a 202 will certainly give you good towing. My motor had a LPG torque plus cam, stage 3 head when it was first built and it was very smooth. 135 rwhp on the |

It was pretty straight forward.
Red 202, dynamically balanced, gas cam, stage 3 head, Electronic VK Comm dizzy, Holley 350 carby, Torco manifold, Impco high flow LPG mixer, Walker Motorvator extractors, turbo muffler, 2 1/4 " exhaust.
It has all cha |
