My buddy has a 78 ford f-150, that is 4x4 and rusty. He bought it for $500 for a beater, trail riding, play in the mud, screw around with truck. Well it has a 400m in it and it good the imfamous main knock. So I tore it down. Well I don't want this to happen again, we are going to put a crank kit in it and have it bored put badger pistons in it, cleveland heads, and it has a summit cam that I had put in it about a month ago, along with a edelbrock streetmaster intake. He never plans to rev it over 5,000 rpm, so will the multi-groove valves be alright for this? Also what oiling mods should I do, I'm running a hydro cam, so should I use any restrictors? ALso, I plan to run the external oil line from the front to the back. Anything else I should know before I put this beast back together? This is my first 335 series engine. ------------------

Post on the 335 engine series forum and ask for EJ. He did up a nice 400. I am sure he would steer you right. He is about the only guy I know who did up a very nice 400 and he is real helpful.

Here's my opinion;No oiling mods are needed. That line is only necassary if the motor is going to see sustained hi rpm, or more than 8000 rpm. I never ran one on any of my motors, and they would occassionaly hit the 8k rev limiter. Since it isn't going to see either, it's a waste of time and money on that motor (almost all cleveland style motors dont need it). Also, the heads the 400 has (there is no 'm' in the designation), are essentially the same as early cleveland 2v heads. Except, the 400 heads have a slightly worse exhuast port, but they have hardened seats. And as for the 335 forum, there is A TON of mis-information spread on that site.

Hey KV, thanks for the advice, I have a set of D1AE-CB cleveland heads that I was going to use on it. I was planning to do some porting on them, but nothing major. KV do you think the stock multi groove valves will be o.k., or should I have single groove valves------------------

Here is what I got from him. Hope this helps.
On the 400, it's simple to make power, get .030 over flat top pistons, made by Dyno-gear, arp rod bolts, high volume oil pump, then a mid range cam, like a 351CJ, that makes power from 1,500 to 5,000 [don't want to wind a stock 400 much over 5,500] and you don't want a big cam, because a 400 makes it's power in the lower rpm range, it's a torgue motor, like a 460. Then for heads, use the early 400 non smog heads, which are the same as the 70-74 2v cleveland heads, then with headers and a 650-750 carb, he'll make 375-400 hp and as much torque as a 460.

I've ran them on low rpm motors (5500 rpm shift points) and never had any problems, but I know of other guys who have had problems with them. I guess it all depends on how much he wants to spend.
