Someone asked how you get to 9.2 compression, .030 overbore, magnum heads, and you can use 318 magnum pistons that have a taller compression height in a LA motor they work fine, as 5.2 and LA engines have basically the same rod You would want to re-balance but that's always a good idea when...

I think I am going to go with Oregon cams, we discussed a few different options including re-grinding my vintage 318 cam that is good shape and made of better material. I like the idea of something not mass produced from who knows where.

Well I am not a big comp fan either I have heard of lots of problems with them, although to be fair it's probably the lifters that cause most problems these days. A lot of this stuff is just not made of good material and is not sufficiently hardened. I have though about going roller but the cost...

I have the Hughes springs and retainers on the magnum heads with .510 lift the seals just clear so I wanted to stay a little less then that, that's why I was thinking around .500 max . My current 318 runs a factory 340 automatic cam which is 210 & 220 @.050 runs good but I doubt the compression...

I haven't heard 3/4 race for a while. I had thought of running something like the 340 manual cam but comp has similar stuff at .050 duration but shorter overall duration in their dual energy series. Another consideration would be I would like to be able to not have to run premium gas so perhaps...

By the specs I bet that would be a good runner probably too much lift for my 1.6 rockers without cutting the guides down.

This will probably open up a can of worms as this subject has been well covered but I am interested in some recommendations that folks have actually built and ran. Here are the particulars. Care is a 73 Dart swinger 3.23 geared 25" tires factory high stall converter in 904 with a TF-2 shift...

I have backing plates and some misc spring hardware no spreader bars or drums

Probably because most of the 70's cars with 8 3/4 rears had 11" rear brakes, I am not sure I have seen one that didn't except for the original A body 8 3/4's that used special narrower brakes and drums

For 2.5 brakes the offset is the same, 11" brakes I used were 11X3. There is no standard Abody rear end with big bolt pattern you either have to re-drill the axles,or get custom axles. I used a station wagon rear and had it narrowed and the axles shortened and re-splined so I could use the...

The 8 3/4 rear from the donor station wagon that I had narrowed and the axles cut and re-splined had 11" brakes so that's what I used. Got to big bolt pattern and correct offset to center the bigger brakes and axles that way.

They will fit fine I had 14 " wheels when I built my rear end

Sorry I was out of town until today, what I have in the shed is 11" backing plates with some hardware. I thought there was some 10" stuff there but it must have been used up somewhere.

I will measure and let you know

I may have a set of 10" backing plates if your interested in pieces. Let me know and I'll verify the size for sure, I ended up going with 11".
