best engine to build!!!!!

Like previously stated......roller cam 360 block.

Sourced from 88-91 D250, B250, and 4x4 Ramchargers ONLY....not available in ANY other trucks/cars.

Right now (2011) is prime time to find this 3 year production block.

They come with 308 casting W2 style "raised exhaust port floor" 1.88intake 1.60exhaust valves, and flow "pretty good" in stock form.

They have 7/16 pushrod holes....all other SB heads have 3/8" push rod holes.

Roller Lifters....which means you can change cams and use the original lifters over and over.

They come with HV oil pumps..and double roller timing chains.
(I would replace with New Parts for a Build though...and go as far as to add a MP 3.9/5.2/5.9L SB Timing Chain tensioner to rock steady the timing)
Here is the one I used on my 89 Roller 360


With a cam of approx 230 duration and .550" lift, a good P&P on the heads, stock CR (8.8:1) a AirGap or Good Single Plane....you would be knocking on 500 crankshaft horsepower on Stock Pistons and Rotating Assembly....with headers and proper sized exhaust system (no 2" duals here....this build recommendation assumes 2.5 Pipe and straight through mufflers....like Glass packs....no flowmasters here)

The camshaft determines the amount of air the engine will move.

There is absolutely NOTHING wrong with using a Hydraulic Cam LA (Non-Roller Cam) instead.....meaning a 360 from any year 72-87........except for the fact that the Hyd Roller is quieter, and you can reuse the lifters on cam swaps, and the less frictional, rotational mass.


But in the end of all this....your still going to end up like the rest of us.
Frankly, 500 crankshaft horsepower translates to 415 wheel horsepower.....which is "fun" but its not the kind of power that will impress everyone.....Breaking the street tires loose from 0-20 mph is cool....but not the crazyiest amount of power seen these days.
While its fun and all....it doesnt take long to start wondering what to do to get that next little bit more power cause that 2011 5.0 Mustang was a little stouter from a dig than we thought....and you'll be regretting not stacking the power more to your side...What you need to do is Single Turbocharge it..70 or 76mm T4 based ..and stuff another 15psi and 800cfm of air through it....and you can finally realize what its like to harness 4 digit horsepower/torque on street tires and pump gas....blazing BOTH tires from 60-70mph rolls and accelerating so hard it scares everyone who ever feels the boost kick in.

This 1969 Dart runs Easy 10's on a single turbo SB.
