Blaster Pro-Tec exhaust manifold M10-M8 bolt dilemma

[96superjet]

Have the opportunity to buy this used Pro-Tec 760 exhaust manifold which of course uses M10 bolts. I haven't yet picked a motor for this Blaster build (I have both a 701 61x cylinder or 760 62t cylinder I could use).

If I go with 701 61x, Pro-Tec offers some kind of hybrid M10-M8 bolt to make up for the larger bolt holes, but they want like $8.95 per bolt...

I could use the 760 62t cylinder and move on, but I've never run a 760 in a Blaster.

I'm looking for either more cost effective 61x bolt options or reviews from people who have run a 760 in a Blaster (not for racing, but for wave jumping).

5/16 inch brass ferules from any hardware store is what I used in the past and it worked perfect.

Use m8 bolts.

Scott, this is what I used on mine. Fit perfect, pressed these into the manifold, used the 8mm bolts. $5.00, done. And if you ever need to use the manifold on a 62T, just pop them out and you are good to go. http://www.ebay.com/itm/New-Longboa...544957&hash=item20cb8901d8:g:AVcAAOxy4YdTWhAV

Cool... are they metal or some other material? Also, are they the appropriate length or do you have to cut/grind them down shorter?

Metal, I didn't have to touch them, just tapped them in with a soft blow hammer.

I made one of these for each corner of mine today. Just strips of copper around the 8mm bolts. Regular 8mm bolts in the other holes.

Mine is a 61x manifold someone drilled out for 10mm bolts.
