hey, its all a matter of opinion! i just wanted to know what i could get out of each of these engines power wise w/just a cam and intake. the cam would be a cheap summit cam and the intake would prolly be a weiand (for the 400) or a stock 4v for a 302.

JIM1979 what after market part can you get for a 302 that you can't get for a 400? And going 360 on a low deck small block requires an after market block and to get power out of a 302 after market heads are pretty much required. Here is a 400 build that beats your 302 in torque for less a lot less money heck I bet you could duplicate this for what your 306 costs.

I will admit that some parts like EFI and superchargers are more expensive for the 400 but I really don't think that kind of stuff was on the original posters mind.

I had a 77 400 out of a T-Bird with low miles on it, added a carb and in take and noticed squat. My opinion they are good for one thing... a boat anchor. they have low compression and the heads suck. I now have a 79 with a 302 and a C-6, at first it felt the same as the 400 and was getting about 12mpg then added a Weind intake and Edelbrock carb and am very happy with the results. I'm now getting between 17-18 mpg. Just my .02.

honestly, u expect to get an instant 100 extra horses w/just an intake and 4v w/ the old p.o.s. retarded 77 cam?!
the 302 has a wayyyy shorter stroke than the 400, so when it comes to mileage, the 400 can't compete when the 302 makes 75% less intake strokes over a distance than the 400 does!
it's not like i'm looking for 30 mpg here, look at the truck!
15 would be nice, 18 would be amazing!
i'm just looking for the best bang for my buck... and so far, it's turned more into an argument over what engines better!
i dont care about the reputation of either engine... if i did care about the rep, i'd have just thrown my 429 in it by now!
show me some hp and torque ratings w/just a summit cam and 4v intake on both engines...
and mileage, if possible...

Does anyone know why they quit making the 400/351m years before the 302/351W?
That's not a bad build for that 400m. So taking 15% off of that total of 339 at the crank would give you roughly 288hp at the tire. Not bad.
It is all a matter of opinion. I work hard for my money and will definately keep sticking with my windsor based engines.

You can probably get any aftermarket part for a 400 as you can for a 302/351W. But hands down, you have more choices of any aftermarket parts for the 302/351W engines. Hands down.

And keep in mind this was built for a drag car......not a pulling truck.

$2500 306
1500 heads
309.99 intake from jegs
269.99 cheapest holley dual feed 750 I could find at jegs
100. low balling cam because you were not specific in your post
So you paid for all your machine work, pistons, bearings, lifters, headers, and the list goes on for $320.02. Wow where do you shop?

I want to hear the opinions.
500hp for $3500 is a great deal!!! Do you have the parts listed to build that engine?
