Thread: Holden Motor Question

Here's a pick of the 186 that I removed from the series 1, these bores are pretty thin as you can see there's a piece missing, It also took the top off the piston.

That is a serious hole in the cylinder wall! Unbelievbly I got an email from a bloke saying he's got a 202 Black with an auto box and he said he's willing to sell it for $50! I don't really want an auto but if he doesn't want it I'll take it a maybe sell of the auto and the good parts off the Red motor. He said it would need a rebuild but a fuel injected motor with electronic injection out of a VK Commodore isn't bad for $50. Auto 1 got back to me and they said they can get me a full set of pistons .080 oversize for $200 from Perth. I'm very interested in the Black motor but I don't know what they're like reliability wise and what they're like to work on so be interesting to look at as an option.

Mate for $50 it's worth it you might even make a couple of $$ selling the trans, you can fit a carby manifold to the 12 port head and not worry about the EFI setup, being alot younger than the old red motor might also have better water jackets but I believe you would have to fit the vacuum hoses up to the charcoal canister because of emission laws (it may pay to check that out).
The old 186 block has seen better days, I'll remove all the good bits and scrap the block.

Cheers Chris

BUY.

Steel crank. Use.
12 port head. Use.

Find set blue rods next and the piston and you're set.

Or just use the black engine with blue rods as the black are worse than reds.

Auto 1 are going to give me a ring and let me know what they can do so I hope it all works out. I read you can't use a 186 block with 202 crank but not sure.

I believe the drag racing guys put 202 cranks and pistons into 186 blocks.
They machine the journals down on the crank so that it fits the 186 block and apparently this combination is a far better engine for pulling revs.
The 202 pistons have to be used as they are shorter from the gudgeon up. Another option they do is use the falcon 3.6 lt (221ci) crank and machine the journals to fit etc. I was in a local machine shop recently picking up my Landy engine parts and one of the automotive machinist who is into drag racing showed me a modified Falcon crank he was setting up.

Cheers, Mick.
