The above is the cam Delta ground for me and is the cam Jose uses Think the Delta part number is DEL-111 for this cam. My cam was ground on an after market cam one of the Crane pieces a stock cam cannot be ground to quite the specs as listed above but should be pretty close. Which may be a good thing for you if you build the 2.9 crank motor. Reason is the piston on some versions of the 2.9 crank motor stick above the deck of the block and with the lift of this cam you could run out of valve to piston clearance in a hurry.
I like the idea of the 2.9 crank motor it gives you more displacement and compression on the cheap. If I recall it gets up around 10 to 1 or a tad under that. Of course that is on the cheap provided you can score a 2.9 crank for little of nothing and have the snout machined for reasonable and the balance is not to far off. I would run the numbers on cost and then if it is any where near oh say $400 would forget the 2.9 crank and go with a set of custom fordged pistons with 9 to 1 compression.
Head work is the real key to making power on the 2.8 IMO, the ports on these heads are a mess really and a pain to port.
I assume you are refering to the Pruit rocker mod when you say floating rockers. My advise is forget it and just get a set of re-worked rockers from Delta. Work fine last a long time and are cheap to buy.
My motor has the cam, head work, big valves, custom made bronze guides, lightened rods, arp rod bolts, balanced, Offy intake, intake port matched to the heads, block decked for equal deck height, Crane HI6, Isky valve springs and retainers, Holley 390 reworked by a guy who knows his carbs and the car will make your butt pucker believe me, it will go side ways right now if you do not watch it and that is with below 9 to 1 compression on cheap gas.... I have around 3 grand in parts an machine work in this motor and that is not counting the core engine or any labor for the port work which I did took around a week and a half to do plus I assembled the engine myself. I fgure you could spend $4-5k if you had all the work done to re produce my engine toss in the 2.9 crank mode and the floating rockers and you could add a bit to those figures.
Two things for sure you want with a non-stock motor traction bars from day one, wheel hop will break things like right away and hardened axle keys or an 8 inch rear end actually you want these things with a stock motor because breaking stuff is no fun.... I know... blew a clutch...spun a hub....and busted a T5. I figure I spun the hub on day one because I did not put the hard axle keys in and figure wheel hop is what weakened first gear and finally killed the T5.
Just rambling just my opinion, I tend to get carried away when I build this stuff and sometimes go over board and wish I had not, wish I had listened to Jose on several things and learned the hard way... ok rant off got to go finish bolting my car together.
