How much horsepower should a 410 v8 make?
How much horsepower should a 410 cubic inch v8 make at 10:1 compression?
I'm building a ford 400 V8 with stock bottom end 4" stroke with stock 6.58" rods bored.040 over for a total bore of 4.040" and decking the block with zero deck/piston clearance with stock 74 cc open chamber heads with polished runners and gasket matched and a crane cam p# 523901 conventional flat hydraulic tappets which should put me right at 10:1 compression. An edelbroc performer 400 Dual plane intake manifold with 1" open plenum carb spacer and either my Holley 600 cfm 4 bbl or my 750cfm quadrajet. I'm putting long tube headers with an open exhaust 2.50" to glasspacks.
I was thinking It has the potential to make 1hp/ cubic inch so around 400 HP is what I'm shooting for in this build. Until dyno runs I won't know exactly but I was wondering whether anyone had any sort of idea of how much HP/ TQ this engine could make with my setup.
I would guess 350-375ish HP. You'd see better results for less money with a 351W. The 351/400M's were boat anchors
I trhink you have made a good guess at 400 HP. The cam you have chosen is good for a heavier vehicle such as a truck but might be a bit weak in a lighter vehicle. Still a good choice for the street. I used to sell high performance parts for a local speed and parts store. Guys would want to put way too much cam in for the car and engine they had. Good balance wins the day. The carbs you have are somewhat small as well. I would op for a 700-750 cfm Holley double pumper if possible. IMHO.
I wouldn't put any $$$ into a 400 M block. Swap to a 351 Windsor - More parts available.
With that cam 325 would be optimistic
300.
- Will a new exhaust actually increase horsepower and fuel economy in my 2001 ford ranger 4.0? I'm looking at the flowmaster 40 series duel exhaust here: http://www.truckexhaustkits.com/ranger-96-04-dual-exhaust-2-25-ma-pipe-flowmaster-40/
- Media and the left are bent on believing Ford no matter what. Will she make up details to make sure her story is believable? So far her only witness has denied being there. Her details are so sketchy they are not really believable. But, Kavanaugh is being roasted anyway. This is just terrible. The point being, she could say ANYTHING at this point and the left would believe it. She can contradict herself (the number of people in the room) or she can flat out lie because we're not demanding any proof. It is really terrible what they are doing to Kavanaugh.
- How much horsepower do my racing stripes add to my car? I'd guess at around 50 but I was wondering if any car guys know the exact number. My car is a 2004 Ford Ka
- How to increase the horsepower and torque on my 2005 Ford Thunderbird? Well I was finally able to buy my dream car. A 2055 Ford Thunderbird which is fully loaded. It has 3.9L V8 that pushes out about 280HP. Well for a V8 we all know it can get much more than that. When I tested it out, it did a 6.4 second 0-60. I'm looking to increase the horse power to about 400. What should I have done to the car by a certified mechanic?
