Ok so it isn't exactly a race engine but it is fairly strong for what it is. What is it? Here's the rundown: '78 360 .040" linehoned/decked, stock stroke cast crankshaft cut .010"/.020" Eagle SIR rods, KB 107's, pocket ported 'J heads 1.94"/1.60" , Professional Products Crosswind intake, Lunati VooDoo hydraulic cam #60404, stock stamped rockers, Holley 750 dbl, garden variety 1 5/8" street style headers, Magnaflow mufflers, etc...
Considering the 9.7 comp ratio, open chamber J heads that were mildly worked and subsequently registered 231 cfm @.480" on the SF-1020, I really wasn't expecting much more than 400 hp and maybe 415 lb/ft at the peaks. I will definately be using this camshaft, in this combination again. The customer reports excellent manners on the street with a good strong surge of power to well above 6000+ rpm. So here it is on the dyno with some data to accompany the above. I feel this engine is very representative of a mild 360 build that should be fun on the street and not breaking the bank. J.Rob

We were obviously having a little fun. Still very interesting though, I thought. Blew the customer's mind. J.Rob

Forgot to mention that this was tested on 89 octane mid grade winter fuel. Up here it's known as MacEwen's gas. Some further testing on Monday but not much. J.Rob

looks to be a very good build for some streetfun with lots of torque down low and good power upstairs something that just hit me on how flat the power goes at 5500-6000 could it be one of these two reasons 1.running out of air basicly from ports not flowing anymore? 2.some kind of instability in the valvetrain? not a profesional just checking if what litle i may have picked up over the years could be the right thoughts

The only changes were the addition of a 1.5" Wilson 4 hole spacer and I packed the intake with snow. Timing was not changed for any pull and remained @ 35 total. J.Rob

Wow making me rethink my cam choice. My build is similar, but i have 2.02 valves M1 single plane, but a comp ex268. That lunati cam really runs well and make power all over the place.

I suppose there is a similar spec cam for BB? I have a mild 383 (stock 906 heads, stock bottom end) that I might consider using one in.
