As of now I don't the heritage and classic are similar. I have a 96 classic and I had a 48 master before. IMO spend the extra on a masters series. I'm going to trade mine for a masters. Deeper drawers are much better imo
If you are going through ddp for nozzles again I honestly dont see the need to go larger than 45's mine are about 50% over and they did 1016hp with a 2900 pulse.
We bend them all the time for our ford twin pump kits. They won't kink if you have a decent tubing bender. We have several lengths of line in stock if you can't locate anything else let me know.
We have used them on 6.0 and 6.4's with bigger singles since they don't spool turbos very well. They do help but at a cost. The ones we use are fully open at 14 psi
from what i understood is the stock rear cover has some flex and can leak coolant under power but at least for me has never been a problem and seems like less of a problem than cap walk to me.
Iirc mine is a 30 psi auto meter ultra lite, I can only run about 13 because it blows past the fca and rail pressure would get way too high at idle. Also I run my ficm dry
I would be willing to let you borrow mine, i just sent it to Evan lb7dirtymax01. if he will be done with them soon he could just send them directly to you, might just want to pm him and we should be able to work something out.
Try to spin slightly lift it, sometimes they are tough as Hell to get them to seat all the way. If you can't get it you can try standing the trans up to help align everything. Hope this helps
