440 is totally dissassembled have a couple questions

[Brightyellow69rtse]

ok well one of the questions is about the cam that was in it i found some more markings on it. theres a na2089  and a 270h10 on the front of it behing where the timing gear goes. its also has redish purple paint on the face of it if that helps at all.

i got the pistons out and one of the bores looks kinda crappy. whats a good piston thats wont cost me a ton of money this is a budget build. im using 452 heads i had some work done to a few years ago. they were milled .050" and a 3 angle valve job.

any reccomendations while its all apart would be great thanks guys

   POST FULL PICS OF TRACTOR GAL and bet ya get tons of help and replys....    if cylinder is to crappy ya may have to bore and sleeve that one. what year motor and has it been ran hard or had any detonasion high rpm,, old old rods are being found to have fatigue cracks are breaking near wrist pins,,all the best on your build

That's a Comp Cams number, 270° advertised duration with 110° lobe centers. Power range is from 1800-5500 rpm.

thanks for the cam id. ill admit i know nothing about cams. is that a good cam? i hope to build a pretty stout 440. im getting new pistons a for it after i get it to the machine shop. im using 452 heads milled .050" with a 3 angle valve job. i also have a brand new street dominator intake ready for it. my car is a 4 speed with 4.10's

i also have this cam http://www.summitracing.com/parts/SUM-6401/

should i reuse either of these or is there something better i should be getting?

Mike, if you're going with new pistons etc... then you might as well upgrade the cam. 

I like the Lunati VooDoo 303 grind for your build.

Bill (440RT) is running this cam in his 440 and it makes very good power :

KB has a new line of Forged pistons that are reasonably priced....those would be a nice upgrade if you need to overbore the block.

ok Ron thats the cam then you never steered me wrong before and ive been picking your brain for years lol.  Ron can i use the same springs with this cam that i used when i ran the summit cam?
when i can get the block outta the cellar im gonna take it to the shop and get it cleaned and checked out. im hoping i can get away with just a hone but i dunno. its .030" over now so i dont wanna go crazy with it.

Mike, the Comp Valvesprings i specced for the old Summit cam will be fine with the new VooDoo grind  

You will need a new timing set for the Lunati cam...it's a 3 bolt upper gear. The Comp Magnum double roller is a great choice and costs under $50  

Keep us up to speed on your progress
