my friend has a 93 mustang 5.0. so it has the gt 40 heads on it and they look cleaner than usual so i think they have been redone. anyways i have those 90 model 5.0 truck heads that don't flow very well. we are going to trade heads as well as his roller cam and lifters pushrods and guide plates for my cam lifters and pushrods. do you think that i should. how much power would i gain frome the roller cam and the gt40 conversion.
Is this an even trade? You should see a fair amount of hp increase from the heads but a lot depends on the cam he is giving you. I know some of the first generation lightning crowd like to use the 5.0 HO cam in their trucks and they think it is a decent power maker. Is your block/cam a roller as well? Sounds good
does your block have tapped holes in the center of the oil valley, between the lifter bores? What year engine? If it does then it will be a drop in deal if it does not then, being your cost concious just trade for the heads and replace your cam. Later
if you are asking if the holes under the intake are threaded, then no i do not think they are. but there are holes. it is from a 90 model f150 automatic
If your block is definitely a newer block you should be able to drop everything off his motor into yours given you swap cams. I am pretty sure about that one. Someone will confirm it I am sure. The 4 holes should be already tapped. Just make sure you have a late model engine, if you are not for sure. You wouldn't be hurting any if you swapped heads with him and purchases a new flat tappet cam designed more for your truck instead of using his stock cam. Later
yeah that is a good idea the cam would be too much work for one day being that we would have to swap both cams into each of our vehicles. it is already going to be a chore to remove heads off of the stang because of the fuel injection
Thanks to the nice rough idle you let me hear I can't get it out of my head. Just kidding. You know as a thought, you could put a ZF or mustang standard tranny in that thing with a little work. Then you could really get full benefit of the cam? I thought of that when I heard the clip, thought I would throw it out there, who knows with a little looking a person could probably find the tranny and clutch linkage for less than a torque converter and rear gears. Then again a cam is $100 oh well thinking out loud, later
i know i thought about that but i don't think it would be good for me in a truck. because of the long shift ratio. if it was in a car that would be different since the stick is so short. i think i am going to get an extreme energy 262 or something and still buy some 2.50 rear gears
Well you know you can get short (throw) shifters. On another note you should be able to find a stock 3.55:1 complete rear axle that would slide right in. I would even imagine you could find a stock unit that had 4.10, they aren't too pricey if you look around. Something to think about. Later
if it still has the tag on the axle i might crawl under and look one day it had a 300 in it before with a 3 speed manual but was converted to a fmx. do they really have short throw shifters for a truck. i did not know. what if i used the stock 3 speed manual tranny. or i know where i can get an 85 mustang 5 speed with new clutch and all accessories come with it for 250. he is selling the motor and tranny with harness and computer for 600 dollars. but i think my motor should make more power than a stock mustang what do you think about the questions
Well if the tranny sounds like something you would want to tackle, you did mention it previously had a manual, I bet the clutch was mechanical or was it hydraulic? Your main issue with the tranny is gonna be does the current clutch pedal gonna operate the tranny are you gonna have to find a hydrayllic sysytem to make it work or is the tranny you mentioned mechancal? Have to look at the crossmember as you may have to move it and or rework the driveshaft. Your motor should make more hp, like mentioned before with that cam your motor probably makes more hp but it makes it way up higher in the rpms so you just have to get there. Another motor with less cam would off idle appear to make more hp but in reality yours would, just higher up. Unless you figure out weather or not the standard tranny would drop right in and hook up personally I would dig around for some 4.10+ gears you will notice a difference in power and put a stall on that tranny. The c6 you have is a strong unit when in good working condition. Let me know how your project is coming together and what you decide, later
