yea apparently troy was using a 3k head, that was shaved alot, I'm not sure however what rocker gear he was using, thanks for the help taz you have been a life saver

Ok so the pistons i have in it atm are what i believe to be 4age bluetop pistons which give a comp ratio of 9.4:1 when used in a bluetop, they are a pretty much flat top piston, and i am recommended a min comp ratio of 11.5:1, i think the dome cc is around 6, but I'm not sure of the accuracy of this, would anyone know where i could find the cc of one of these pistons?

Measure it yourself with a syringe and some water. :P

ok another question, does anyone know how to take off the automatic "clutch" round annoying thing on the flywheel, i have a spare 4k and would like to know how to remove it, other than angle grinding it off

I assume you're meaning the torque converter? You should be able to get to the bolt with a extension piece on a socket driver from the front (fan end) of your engine looking back......

 

If you turn the flywheel slowly you should be able to see one of the bolts, undo, turn, repeat, beats the hell out of grinding it off......

You mean the torque converter?

 

In the bottom of the GB backing plate there will be a rubber/plastic boot/plug about half the size of a pack of ciggies. Pop that out and you'll see there's 6 or 8 (can't remember that bit) 10mm bolts that hold the torque converter on from behind. :P

guys i have another question, my head has a casting number of 81 on it, I'm not too sure what this is, although it is supposed to be a 5k head, any ideas?

also i have a head that is meant to be a 4k head that has a casting number of 4

also the head with 81 on it does not have lugs under the spark plug holes, I'm just going to assume it is a 5k flat top piston head

ok well i have found out i have a 608 Cam Tech cam in the engine atm so i can now tell the people building my head the valve lift so they can find some springs to suit, here are some specs

 

Rough idle, strong upper mid

range and top end, modified engines only. Min 10.5:1 comp ratio.

RPM RANGE 3500-7500

 

Duration

 

Advertised

 

In: 290

 

Ex: 295

 

Valve lift

 

.453

 

so its actually a 4k cam that is in the 5k block, which is strange, i took out the cam welch plug and it seemed as if there was slight wear on it from touching, i spoke to the engine shop and they said it should be ok, also i do not have to run as much compression as i thought i would and will be using 10.5:1, which should keep it around for longer

hey guys another question! whats a good way to get the block clean before i put on my new head gasket?

I normally just give it a clean up with a paint scraper type tool that has a stanley knife blade in it. Just make sure you don't score it though.

is it necessary to use gasket goo? and does that go all over the gasket?

Nope. What brand HG you using? Genuine?

 

I usually give mine a little spray with some "copper gasket" aerosole stuff, but its not neccessary.

I put all my HG's on dry.
