thanks for your help I only want to do this once
If you want 510 hp and about 610 torque with what you have now,6015aa block do not deck it (already short enough height) if you want to drive it on the street, stock 71 crank, DOVE heads, dished replacement pistons (forged or hyperutectic). Makes CR right around 9.0:1. Use the Performer RPM upper end kit w/out heads (all are matched to work together).port match the heads and intake to the intake and exhaust gaskets and smooth out the thermactor bumps in the exhaust ports on the heads. use high volume standard pressure Manley oil pump and drill out the oil entry galley to 1/2" to match pump but be careful to not go to deep. Always a good idea to increase pump volume on the 385 series blocks if you're towing or bracket racing. No need to spend mega bucks on the 1968 - 1971 BBFs they were under rated at 385HP stock (DOVE C or D1VE C heads) more like 410- 425 HP. Had a totally stock(flat top pistons about .040 below deck,stock crank and rods) 71 429 engine that I rebuilt and only cammed it up a bit (Crane camshaft) made 549HP and 624lbs.torque (max values). Had to use premium fuel and 104 octane booster even though I installed hardened seats on the exhaust with stainless replacement valves on both the intake and exhaust. Use a good double roller timing set (think it comes with performer rpm kit anyway). Ford BBs tend to wear out chains and gears when they are run hard and often. Stroked BB Fords are recommended for racing purposes and bragging rights only. I put the above mentioned engine combo in a 71 Cougar XR7 and it is enough to be scary, especially with a loose front end and almost no brakes - LOL! Additionally, shortly afterwards did the same build on a customer/friend 74 highboy 4x4 and he kept twisting driveshafts in half. After about 3 1/2 months he pulle dout that engine and stuffed a mildly built 390 back in it. With the performer RPM kit in it I'm relatively sure you won't have that problem. Glad you're not concerned about fuel mileage though cause it will be a gas eater unless you detune it and use a conservative carb (650-680 cfm) as the performer rpm kit I believe uses the 800cfm carb or spend a little more for the Fitech tb fuel injection setup. While the d3ve and up heads will work ok with decked block and flattops I wouldn't use them as they are severely restricted on the exhaust side. If you must use a set from 72 - up look for the police interceptor heads. Forget CJ or SCJ heads they are not about efficiency at all (you can almost stick your hand in the intake ports. Ford only put them in street cars (tuned down) to comply with NASCAR rules so that they could use them in the Talladega Torinos and Fairlane Cobras for racing. They were also popular in SS and some pro-street drag racing brackets. The Mustang and Cougar CJs and SCJs were very popular weekend warriors as well. However, you have to remember gasoline was only 28 cents a gallon back then and high octane fuel can easily be purchased at your local SUNOCO station. You could actually select octane level by turning a knob on the pump. If I remember correctly it was available up to 110 octane (almost aviation gas). Anyway have fun with your build you will be able to tow single wide mobile homes with your truck/engine combination.
