crustydemon Posted April 8, 2008 Report Posted April 8, 2008 After reading many post I have decided to go with the Hotrods 4 mill long rod crank but I also was not going to do it without porting.I am on a somewhat limited budget and didnt have time to send my jugs in so I found a deal on a very slightly used crank and piston setup with Trinity pro MX ported jugs.First I would like to know why nobody likes the trinity port jobs and what should be done to make it better.This setup came with no bottom spacer plate and did come with a head spacer plate.Does this mean that they were probably ported for the 4 mill and just needs the top spacer for squish or not? Im not going to use it anyway because I got a noss head and will get stroker domes when I decide on the cc I want to go with.To do it properly should the port windows be raised and lowered 2 mm from stock so you dont have to use the base plate?I just want to compare them to stock cylinders to see how they differ and make sure everything is right before I assemble it.Ive also heard that the factory welds on the cranks are no good and they only weld the outside but on the crank that I got it is welded inside and out with 2 beads(tig) on each side(so 8 actual beads)and they look real good. I this something that someone else might have done or is it factory?Sorry for the same old questions but Im just trying to figure some stuff out. Ill have many more stupid questions soon.The search aint worth a shit. Quote
crustydemon Posted April 9, 2008 Author Report Posted April 9, 2008 Any help would be appreciated. I dont want anyones secret port dimensions,just some info on what the heights should measure so I can make sure its right. I would like to start putting it together tomorrow.Thank you. Quote
Wildcardracing Posted April 9, 2008 Report Posted April 9, 2008 It should measure somewhere between 56 and 57mm from the deck to the floor of the exhaust port and also the floors of the transfers if it has been ported for the stroke. Quote

dajogejr Posted April 9, 2008 Report Posted April 9, 2008 I sure as hell wouldn't want to run a spacer on top...that's a good way to snag a ring. Quote
