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

Sheet of the first pull. J.Rob

Here's one of the last pull for today. Not bad huh? J.Rob

Nice motor,

Bullet-proof 440+ hp smallblock, iron heads and hydraulic cam, kickin' it old school and that's WAY KEWL!!

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

Nice engine! Looks like it could would do good in a strong street car.

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

I built one just the same, same KB 107 pistons, same heads, but I went one notch lower with the cam with th 286/276 one

and I used stock valve sizes on the heads....and a preformer intake, eddy carb.

I was impressed on how hard it pulled for what it was....

I was leaving my buddy with his 65 350 vette and my other buddy with his 65 Mustang Fback which had a 302 with aluminum eddy heads, and a bunch of other stuff in the dust!!!

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

I'd like to know what changes were made between the 1st and last dyno runs.

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.

Nice little small block,glad to see you posting this stuff.Maybe I will do the same soon.

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.

Dyno sheet says 830 holley and text says 750.Which one?Is it just me or is the a/f ratio on the first run pig rich down low and still rich up top?
Nice numbers.Gives me ideas for the rebuilt 360 I just bought for peanuts with a 727.
