hi, im still running a 470 in my v 20, ive done a few things over the years an the thing you might add as i did is a set of roller rocker arms , i found them on ebay a few years ago from a ford 460ci engine, they were made by crane cams , they made that ticking noise go away

Proving my point...

MJ has been accused of windtalking do to the fact that sometimes you have to carefully decode his posts to understand what the hell he's talking about. The name Windtalker comes from a movie about Native Americans who were used to encode or decode secret messages in the military. Translating Crocodile Dundee/Outback Steakhouse into Yankee/Redneck/Good Ole Boy and back again I find very similar.

Don't worry Aussie, you're not full of wind, you're just windtalking. :beer:

Why do you have to leave? Several members, myself included, are members of other websites also. If you really wanted to leave, just stop coming here. People come and go all the time. But I really don't understand why you would want to leave. No one's attacked you in any way. As far as I can see everyone's always tried to be helpful with any questions you've had. Yes, there is a language problem sometimes, but it's not really a big problem. I, for one, enjoy your company. and I'm sure I speak for the majority of people here.

Aussie, build that motor back stock. Don't raise the compresion any above fatory. They had issues with preigniton back when we had good gas and revised the spark timing back 4 degress. Leave the cam alone, use a good rocker system. The performer head is a good idea, you won't have dissimular expansion rates like the cast iron head to aluminum block. You may have to increase the size of the heat exchanger to handle the increased heat transfer from teh aluminumhead. Recurving the distributor isn't going to help as most of the total timing is in before you get to cruising rpm, increasing the curve below planning speed can cause preignition. Buy those other two motors you had listed, use the 4bbl intake and oil cooler off of one of those. Put a pertronix igniton in the distributor and a 1 step colder plugs. You will be happy at the peformance with the 3.7 in its stock form. If you want to go faster, put a V8 in the boat. Most of the mods you have listed will work great if the engine was in a car, but in a boat, you will have longevity issues, along with peaky peformance(especially with a heavy boat like a V), don't try to turn the motro any higher than 5000 rpm, the drives don't like high rpm. You'd be surprised how well the boat will perform in stock good condition. I understand your desire to build it bigger and better, but I don't think you are going to get the return from your time and money you are looking for with this combo.

well it will be stock in the sense of camshaft and the comp is 10.1 only makinf it breath better and raise its tork
 
Sounds like you are on the right track. use the KISS method, Keep It Simple Stupid, or the way I usually do it, Keep It Stupid Simple. BTW, if you go to the machine shop with this motor, have them look at the cam shaft bores. One of the issues with the 3.7 motors is they loose oil pressure after they get hot. the problem is the cam rides directly in the block, no cam bearings. There is a service replacement cam bearing that has to installed by a machine shop(cam bore has to be overboared then new bearings installed). Might be worth checking into see you're going this far

well thanks thats good to no i havent pulled the block out yet so they run the cam directly on the block like ohc engines well the oil pressure was good on the engine but will measure the bores of the cam to see how much clearance and i hope there not worn the could put a a big expense on the engine well thanks for that info i wouldnt even of checked them
 
hi guys i have decided to cut the end of the camshaft off and plug the hole in the timing cover and run a electric water pump and the fuel pump is going too replaced with a electric one
 
no reason to do that and you'll only complicate issues, , you'll never notice the difference in hp and only introduce another item to fail.

see the KISS method outlined above

its not for power fuel pumps for these engine arent cheap and i dont think u can buy new ones and u can how long will it take for me to get one a electric pump i would have it on the same day and for the price of one i would more and likely keep a cheap one in the boat as back up and for the water pump i want to elimanate ever having water in the oil from a seal leakage and all new engine run alot of things with electric and how much more load does the water pump put on the timing chain well i dont like the idea so its going to be changed these pumps r that expensive
 
this is the water pump
