hi all,
im lookin at building a new engine for my hj, its got a red 202 in it at the moment, but being a P plater it doesnt really have the grunt one needs to get up and go. was thinkin about gettin a Blue or Black block and building it up from there, but not really in the know when it comes to engines so was wondering if any one could give us a few pointers on some good stuff to put in there, and what sort of power u can get out of them. dont want to spend excesive amounts but happy to spend enough to do the job.

cheers

Luke

For a P-plater there's more than enough grunt available from the old red 202 to satisfy all needs. I've got one in my HQ. I rebuilt it 40thou over, flat tops, mild cam, ported head, larger valves, extractors and a twin carb setup on an X2 manifold.

This is what Id do:

Either use your red block or get another red 202 (just has to be a rope rear main seal block);
Get a blue/black crank and rods;
Rebuild it including balancing to about 9.5:1 maximum compression;
Mild cam eg Crow 35666;
Yella Ter

thanks for the help guys, i have lined up a black 202 complete motor that i might get then go from there. im sure ill be back with some more questions thanks again

Just remember that if you use the black block you'll have to (State dependant) make the engine comply with VK pollution ADR's. That is why you should turf the black block and use the crank and rods in a red block.

It can be done, with mods. I think to do with the crank bearings? Check Street Machine's website, it might be in KB's workshop. I'll trawl my back issues if i have time because i know it's been covered in there at some point.

Only works on 186 and 179 blocks as they have smaller mains.

If we all had the same (good) taste, who would buy all the Fords?

Itd be cheaper to buy a Chev 250 or 292 cube straight six and bolt that in than to build a Holden stroker. It will still bolt up to an Aussie 3 or 4 speed with the right bellhousing or straight to a TH350 or TH400, bolts straight to Holden engine mounts u

byron, just a question, why have you said 9.5:1 compression max? are you worried about it detonating?

In cubes we trust.

Thats about the most youll get a carby Holden 6 to run on todays fuel. Also allows a bit of margin if you cant get 98 octane. Remember what I suggested is a mild cam with little overlap and therefore compression will be fairly high.
