HP guess anyone? Additional advice requested
It is still aways from being done so I can't run it on the dyno at work yet. But :cheers: here is the list of specs: :yesnod::yesnod::cheers:
4-bolt 350 Block bored .040
Stroker kit designed for a 383
10:1 Pistons
1.94 Chevy heads/ported and polished with 68CC chambers (SS Valves)
Crane Cam 5.05/5.10 lift with 2.70 duration
Roller Rockers/Hydraulic Flat tappet Lifters and Z-28 springs
Performer manifold
Performer 795 Edlebrock Q-Jet
Headman Headers with 2.5 in. exhaust (single, thru a free-flow Cat)
The car has a new turbo 350 (about 500 miles ago) and factory 3.08 gears. I'm hoping the torque built in to this engine swap will get it rolling well even with those gears. I like highway driving so I doubt those gears will be changed for a while. If I do change them it will be long after my wallet recovers from the engine....and redoing the trans.:yesnod::yesnod::yesnod:
The cam has a lobe seperation of 1.12 and my engine builder tells me that with the lobe sep being as it is, and the engine being a stroker, the combination will idle well. My objective is torque, not necessarily raw HP and I don't expect to use much if at all, more than 5,000 RPM. I intend to use the stock turbo 350 torque convertor hence the need for good idle.:yesnod:
Anyone out there to challenge the engine builders' statement that the engine will have a good idle because it has the 1.12 lobe sep. cam, and it being a stroker motor?? :confused: We in fact, looked for a 1.14 lobe sep but he wasn't satisfied with what was out there so we went with the Crane 1.12

I can't find that cam on Crane's website. Is it an energizer, powermax, or what? It sounds like a powermax, but... anyways.
That cam has tons upon tons of duration. If it's a flat tappet, I'd have to believe that those duration #s are at .050". No flat tappet would have that much lift at 270 seat duration. For your goal of a "up to 5000 rpm" motor, this cam is way out of the way. Are you sure about those cam specs? They don't sound right at all. With that much duration, the idle/ride is gonna suffer greatly as well.

*edit* Well, 270 @.050 sounds like too much for those lift numbers. Could you find the cam part # or tell us more about it?

I'll verify the cam specs tomorrow when I get to work. Sorry but I think it's pretty close... :smash:

359 HP @ 5000rpm and 435 ft/lbs of torque @ 3500rpm with headers and mufflers. On engine dyno with open exhaust no mufflers etc. 385HP @5000rpm and 446 ft/lbs of torque @ 3500rpm

OK them's numbers I could probably live with! That would put me at about 300HP to the rear wheels which is three times what that ole' tired 145K motor that I'm driving it with now, probably has! :smash: :cool: :cool:
