Carl will sell you a mighty 1"x1" strap on and if he has them he'll sell you the bolts to suit.

Do you need a centre main strap? Unless over 7500rpm is planned I wouldn't bother.

I use the Fortech strap on mine....nice because it doesn't require any machine work on the cap & comes with the extended arp bolts. Probably not totally necessary, but I do like to bounce on the red-line on a regular basis!

That is thanks to my pals at Seven Enterprises out in Auburn, CA here in the US. They do a hot chemical bath and bead blast on all of the stuff they send out. This was one of my spares that looked like one for the scrap heap before they got ahold of it! Too bad I couldn't do a good clear coat and keep it looking that way!

Eric, do you realise that strap will offer minimal support for the centre cap. you may as well have fitted two extra thick washers as thats all you have dome in effect,

sorry to piss on you party but that strap is all but useless,

Always happy to hear constructive thoughts...especially from someone with your obvious experience....

That said....what are your opinions on the strap idea....necessary or not? I'm sure that the one that replaces the entire center assembly that has the 2 additional bolts would be the most effective, but are there options for something without the need for additional machine work?

Also...if it matters, this one does fit tightly over the edges of the center main...it doesn't just float on top held by bolts.

Has anyone ever measured the centre main after machining for a strap?
Selby brought this to my attention and said most of the caps he's done have distorted and needed line boring.
I run a 4 bolt cap now and must admit it seems to rev more freely but that could also be down to the new lighter pistons with thinner rings

I seriously doubt it!

Carl - can you supply those CAT bolts and washers in a length suitable for the 1st and 3rd main cap?

Eric, having seen the outside of your engine a few times the inside is even better !!

Does the Fortech strap have a few thou of interference in it to make it bend down at the ends, or is it a flush fit ?

Metric is for people who can't do fractions.

To be honest I don't really see the point in this. The originals are more than up to the job. We only replace the centre ones because the originals aren't long enough when a strap is used.

I have used the standard 1275 and 998 A+ bolts on the 4 bolt cap on my 'new' block. The 998 A+ bolts are just a little shorter. the four bolt cap still needs a little shaving off each 'pad' to get the correct grip length. Is it so difficult to design a part to take advantage of easilly available standard bolts that are more than up to the job?

This is the exact reason my engine has a 4 bolt centre main, as I had the original faced off for a strap, and it then went tight on the bearings.

I have seen a couple of 'proffessional' engine builds now fitted with a strap, only to find that the center bearing is tight. One needed honing and the other was a simple case of inverting the strap itself. Which, highlights the problem.

Personally if you are going to the expense of a full on line bore, you might as well fit either a steel cap or a 4 bolt steel cap,

This was my conclusion, as I had to have it line bored, I decided to make the most of it and have the caps done too.
