360 Build

[273]

What might a small hydraulic roller cam do in a 360?

Here is a 360 Magnum with a stock compression rebuilt bottom end, and slightly cleaned up stock Magnum heads, with a 265/273 advertised, 216/224 @ .050", .506"/.506" lift, 114 LSA hydraulic roller cam and using an airgap type dual plane with a carburetor.

RPM.............TQ/HP

2700..........362/186
2900..........365/201
3100..........392/231
3300..........403/253
3500..........414/276
3700..........422/297
3900..........427/317
4100..........427/333
4300..........431/353
4500..........427/366
4700..........428/383
4900..........420/392
5100..........407/395
5300..........396/400
5500..........384/402
5700..........368/399

Nice
Very streetable package

I was thinking of down grading my 380hp create cam to that one but bought Rhoads lifters instead. Figured it would drop my duration to about there under 3500rpm best of both worlds hopefully. Plus upgrading to the airgap.

Hi all. We’ll I’ve asked for advice on a 408 stroker build and now it looks like I’ll need to trim the budget a bit. I’ve found a 87 360 4 barrel our of a 3/4 Ram for a sweet deal. The motor was removed from the truck in great running order not long ago. My question is I plan on doing a complete rebuild on the engine with a rebuild kit from Summit. It ships with Hyperutectic pistons and all the rest to freshen it up. I’ll probably keep the stock 1.88 heads for this year along with my new Air Gap intake and Doug Headers. Can you guys offer me any advice on what parts I should use to build a nice little torque street engine? I have 3:23 sure grip now with a 904/ 2500 stall in a 72 Swinger. A gear change maybe in order as well. Sorry to keep bouncing around but this looks like the direction I’m heading. Stroker will have to wait.

The gears aren't going to limit Your cam choices at all, that 2500rpm stall converter is tho'............................................

Speed-Pro Hypereutectic Pistons H116CP

These are a good piston also...but the KB107 would be on of the list.......

As my dyno carb, the Q950 Quick Fuel, is now on the shop truck 452, the 850 Mighty Demon is what we used.

I've given up guessing tq/hp numbers and just stick to what I've observed.

I agree. The converter is much more important than the gear ratio.

A buddy of mine ran the mopar purple cam with 272/455 lift cam in a 318. Thing ran very strong. Very nice torque. This is another good cam. Rumble is correct the stock 340 cam is kind of lame.

this is good advice on the MP cam. I ran 13.30's with this cam in a 360 in a '74 Dart Sport with 3.23's and a 28" tire, stock 727 and TCI converter. Car weighed about 3300 without me and 1/4 tank of gas
