Re: New pistons 73g heavier

I'm going to be ordering these trend pins at 88g that's a saving of 42g so I'll be only 31g underbalanced so I'm sure that will be fine, unless for some reason this pin isn't a good idea in a street car ? Also I couldn't see the specs on the trend website but the seller confirmed the weight at 88g ...

Sorry. Methanol as a fuel never occurs to me. They sold M-05 (methanol-based "Gasohol") here for six months or so before changing to E-10; back around 1980--'81. I've never had a methanol-fueled race car.
Since moving to methanol I will never move back! :)

Re: tall deck and intake spacer plates

Whatever you decide make sure it will hold up to fuel.

If youre going to be pulling the intake, you can use small screws on the spacers and mount the spacers to the head, so they are part of the heads, enabling you to pull the intake off.
Thanks! will definitely do that. I was thinking of dowels to keep everything aligned. :)

Re: tall deck and intake spacer plates

Thanks for the reply... I have seen a picture of an engine with the spacers and there was no gaskets just gray rtv, like ultra gray. That would have to be difficult to remove I would think.

The sbc Iron Eagle block requires the bbc oil pump drive shaft. :D
You are referring to the OAL.
As specified in the block spec/instruction sheet to use BBC oil pump drive shaft. I guess it could be used as a generic reference to OAL.

Thanks for the reply!

Re: New pistons 73g heavier

"5 + 5 = 10 grams. 50% of weight for reciprocating is 5 grams." Roger on that. After 4 martoonies, thingz get off a bit. For vintage circle track engines, we go for as light a bob weight as we can get. I have taken more than that off of forged pistons many times. From just looking at the picture, I...

Re: What ever happened to Quality control?

I have used rails with no dimples. After a year and a half that engine has not came back with any issues. I can say that the rails do move. Thanks for the reply! I have resigned myself to the fact that there is no way I can make the deadline with these issues that have taken hours from my day to ad...

Re: New pistons 73g heavier

Get the lighter pins. The rest can be easily taken out of the pistons.You will need a mill for that. If you can hit the old weight within 5 grams, (10 on bob weight) it will run with no problem. I don't think you will be able to get another 48 grams of aluminum (73 grams - 20 grams for pins - 48 gr...

Re: New pistons 73g heavier

No... Do not fill the holes. Let the shop do whatever needs to be done. I always ask myself... If I don't do what I know should be done... is it worth risking hundreds or thousands more if it fails? But that's just me, myself and my wallet arguing out loud when I am by myself. :lol: The biggest prob...

Re: Do pushrods generally bend in the middle or near the lifter end?

The middle third of the pushrod is where all of the bent or broken pushrods have failed on both sbc and bbc that I have experienced. Assuming as others have said... with no interference issues.

Re: New pistons 73g heavier

It takes A LOT Aluminum out of a piston for just a couple of grams. Unless you have solid domes and can removes a considerable amount from either side you are not going to take off much weight. Not sure exactly what your application is but be careful going with a pin with less wall thickness, call p...
