Appears to be a virgin bore 😊

Strip off the head of the 202 for HD & it appears to be a virgin bore, the head gasket even has Holden stamped into it.

HR 50th Engine rebuild

Finally the engine coming together. About 12 months to find a virgin Block, six months waiting for Pistons etc. Still it'll be worth the wait when I put the foot down on that first drive.

HT Alternator bracket

Hi Guys. I am in the process of putting a 304 into a HT and have come accross an issue which i am sure has been solved by someone else before. The standard 304 Alternator bracket is too low and the alternator has no room for adjustment before hitting chassis rail.
I have heard of some guys putting in early commodore brackets that are on the drivers side. My question is, are they up higher and will early commodore (assuming 308 engine) bracket fit on a 304 head?
any information would guide me in the right direction.
thanks guys

Kingswood Wagon Hx

Ive been looking at kingswoods for the past 5 years and they have grown as one of my favourite cars. I knew one day I would buy one and recently i bought a 77 hx holden kingswood wagon. It has a 253 with m21 4 speed. I was really wanting to get a bigger engine for it but I'm 17 years old and money is very tight from buying the car itself. Just wondering if anyone here had a motor or info on where to get one.
Cheers, Ryan

Running hot and using lots of fuel

I have a 1979 HZ 202 red motor that has recently started running very hot, using lots of fuel (1/4 tank to 40ks) and is hesitating/pinging at speed (100km/h). I can't find any fuel leaks and I haven't messed with the carby so i can't put a finger on an action that i have done to explain why it's started it. Does anyone have any suggestions?

I have a blue 202 and I'm going to run a Yella Terra alloy head (INLINE 6 BLUE/BLACK ALLOY CYLINDER HEAD (56CC) & STREET TERRA (HYD) ROCKERS (HEAD & ROCKER PACKAGE), triple Webers, straight cut timing gears and I hope to use the rods from the blue motor and the push rods if I can.
