Fox Planning on building my foxbody and was wondering if I can get any tips or anything to watch out for!

  • Sponsors (?)


Hello I’m new to the forum and would like some advice! I plan on building my foxbody for LMR, I know it’s a pretty tight deadline but I felt like if I gave myself a date to finish by it’ll actually get done!

HIC - I plan on doing a gt40p top end swap, I have the heads getting rebuilt with a valve job, and the upgraded springs the P’s need as well as the lower intake getting drilled and tapped, I plan on getting a E cam with new lifters and 1.7 rockers but I most likely am going to hold off on this till after LMR.

Ignition - I currently have a MSD 6AL2 with a msd ignition coil I have a 2 step button set to about 3000 rpm currently and I set the rev limiter to about 5800 I will adjust them to the e303 once I install it. I also have a Bama 4 bank eliminator chip which has 3 tubes already on it but I plan on getting a wideband sensor to see how my cars AFR is with each separate tune!

Exhaust - I have some Mac long tube headers I was able to get on market place as well as a X pipe and 2 knock off super 10’s, thats all I have for

Suspension and rear end - I currently put new bushings in the control arms (I do not recommend this it took me about 7 hours and a lot of cursing) and upgraded to KYB struts and shocks, with BMR lowering springs (fighting the springs currently hopefully I can finish everything up tonight) I’m thinking of getting rear control arms and pulling the rear end and throwing in 3.73 I got off marketplace I currently have 4.10 and it sucks on the highway but they’re a no problem with them.

Transmission - I haven’t looked much into transmissions but I do know I want to get a TKO and it’s supporting mods like the bell housing and clutch and flywheel. I currently have a T5 I’m not sure if it’ll handle the power without the cam just with the HIC and LT headers

Bottom end - as of right now I’m thinking of keeping the bottom end stock I’ve never really though about what all has to be done with it. Will the bottom end be strong enough to handle what I have planned or what would need to be done to make it strong enough?

Is .530 lift to much and will I run into any piston to valve clearance?
Will the 4 lug be able to handle the power and would I have to do anything to the rear end?

I tried to make this as neat as possible, I’ll take any feedback wherever I can this is my first time building an engine or just a car in general besides throwing some long tubes on my 93 flareside. If you have any questions for me or anything please ask I’ll keep checking the forum daily. Thank you if you take the time out of your day to read and reply I appreciate it! I’ll add some pictures of my foxbody just in case you wanna see what I’m working with!
Sounds good. If your sticking to the 302, rule of thumb is 3.55 rear end gears for a standard and 3.73's for AOD's.
 

At the very bottom contact info
Not sure if he's on here any more.Tmoss was an older gentleman with a 5.0 in a Volvo SW. I bought the intake off him. There was also a guy on here that sold worked stock 5.0 heads. He took a lot of metal off of them. Gave them a triple angle vavle job and put HD springs in them. Name was Thumper. He sold a lot of them on this site. Thumper heads.

Yeah Tom’s son is doing all the porting now. Same quality and his dad passed the knowledge down.

Tom ported a Cobra upper and lower for me 20 years ago and it made a huge difference.

His stuff looks legit. I ported my own intake and heads... we'll see how they do. I have experience porting 2 stroke engines, so I knew what I was getting myself into.

Hey guys been on hold with the project but got some good news! N41 is coming in tomorrow with some trick flow lifters as well as a accel distributor (mainly for the steel gear but thought might as well upgrade it) I have a 6al2 msd system and I think it should be compatible if not please let me know! I currently have taken apart the top end and got all the rockers off just need to driver side bracket then the heads should be able to come off! I want to pull the engine but aren’t to sure how I’m gonna do it since I don’t think I’d have enough space to pull the tranny as well is it possible to pull it and leave the tranny in? I also have a diff that I got off market place a couple months back is this still good to run? It kind of looks like the pinion was a bit to close to the carrier I don’t think much of it but want to be 100%.

Also any tips on the whole install process for the whole top end and cam it’d for sure be a lot easier if I pull the motor, I have a cherry picker but I’m clueless on how to use this thing. Any sort of reply is appreciated thank yall very much!

You can totally do it all with the engine in the car...that's typically the prefered way unless you want to do a complete reseal or mess with the bottom end too.

You also don't have to yank the trans with the engine either.

I did the whole top end of my engine with it still in the car, including the camshaft. If you still have AC and it's in good working order that might make it a bit tougher with the condenser still in the car, but for mine without AC at the time once the radiator was out it was easy and I had plenty of room to swap the cam.

Im currently doing it this way the AC was discharged and the clutch was taken off so I just unhooked everything and took the condenser out! I also ordered a smaller belt to delete the smog pump I’m currently working but man I’m excited to get home and drop the pan a bit to take the timing cover off! Would I be good to just match the 2 sprockets dot to dot? Also I noticed my harmonic balancer doesn’t have a white mark for the timing but it does have a groove cut out in a line would that be for weight or could that possibly be the mark?
 
A stock balancer will have hash marks and tiny numbers with 0* marked and again 10+* with little hash marks in between. There is also 10* ATDC but goes no higher IIRC, that, of course is the wrong way, most times the stock balancer is covered in crud and may be difficult to find, I always line up 0* on the pointer, make sure #1 piston is at TDC (or damn close) with pointer then disassemble, oh, and you'll have a ton of fun snaking an oil pan gasket on without pulling the engine, it can be done but I'd pull the engine, leave the trans in, I just did it on the Junk Pyle, pretty much by myself.
 
Try a rag with some WD40 on it and wipe the outer face of the balancer. If you still cannot see the marks then get a wire brush and clean up the outer face (may have to wipe it down with the WD40 soaked rag as you go) you should see the marks. When you see the marks then clean up the outer face with some brake cleaner on a clean rag. Let that dry and then use some white paint (paint pen works best) and mark "0" and "10" BTC.

Factyory timing with the spout connector out is 10 BTC. Most set it at 14 BTC but that is a preference thing.
