someone suggested an electrical water pump to eliminate lag from the belt, but i figure thatd require a diff belt setup, and a bigger alternator to handle the extra load, and considering im doing the electric fans ill already have a decent increase in draw from it. electrical pumps are good for crazy power motors with small space right? should ji ust keep the mechanical one?

 

Over the years the only cars we put electric water pumps on were track only cars where you want every bit of hp you can get. Stick with a good quality belt driven pump.

 

I would also stick with a belt driven water pump. One option is buying a parts truck with a 351 in it, tear it apart and send off to have engine, trans rebuilt how you want. Then install into your truck. While I would recommend the 351 ( I love mine), I think a built 302 would do you just fine. If you said you towed or went off roading a bit, I would push more for a 351, or even better a 408! (bored and stroked 351). but honestly, I think a 302 will do you just fine.

 

Have you looked at 347s?

 

I havent, usually seeing those made by ford racing which means $$$$

 

Just glanced at some 400hp 347s. Guessing you recommended it due to it being a stroker motor. Only question I have is will my stock 302 efi intake and fuel setup be a good fit? Also not too big on wanting to get a new ecm, esp since the 306 I was looking at is also rated at 400hp (obv the 347 has a better power capability and strength internally). Send some suggestions if you can! Thank you sir

 

I recommended it because its a stoker, which means more tourqe and hp! haha but as far as what your sd set up can handle, im not sure but I know its not a lot. Youd need bigger injectors for 400 hp anyway, 30 lbs injectors, and I don't know much about what the fuel pumps can handle, but im sure you will need ones that can supply a little more. Then you will need a maf ecm, and have it tuned to your engine. That's with a 302 or 347. I seem to remember reading about people setting up both fuel pumps running at once, but maybe that was a dream or wild thought. Im sure its very doable though.

 

yea thats getting more into it than i have time to. if i had the extra time and cash to run a better fuel setup, as well as intake id honestly just do a 750cfm carb setup with the 347 and a mechanical fuel pump off the block, but considering our trucks are hell with those dual tanks, dual pumps and switch nonsense i think im going to just run the 306, transfer over my efi intake and fuel rail and flash the ecu with a new chip. id do the 347 but then that would mean id need to drop the tanks, put $$ into the pumps, lines, injectors, tune and by the end of the day ill only get an extra 50-60 hp (which isnt bad but not worth it). any ideas on whether to gear the rear differently? i drive the highway daily to work, thought about getting one of those mini transmissions that bolts on the back of the tailshaft and gives you overdrive for every gear electronically. anyone use those? gearvendors is the make if im not mistaken.

 

read up on this, i think itd be worth it, especially if i ran an aggressive rear gear setup!

Im not sure on th gearbox, no experience with them or know anyone who has, but have heard of them. However, I do know of people taking motorcycle engines, putting it in rock crawlers, and bolting up something like a jeep transmission to the rear of the motorcycle engine and its gear box. so you could have gears1-5 on the motorcycle gearbox, while running first on the jeep transmission for example. Gear ratio that I would go with heavily depends on engine power range, tire size, and use of the truck. And as far as the 306, it will still be a good bit more peepy than a stock and worn 302, I just wanted to offer you more options and make you wonder if your making the right choice even more! lol
