In the process of a wire tuck and I totally forgot where these 2 wires get connected too.. anyone know?
Ok guys I think the vision of what I want is finally coming together. I'm keeping my notch. I'm getting it painted. And now I'm moving forward with an engine build. I saw the top end kits on LMR for a 302 but would I be better off buying a 351 block and building from there? What's the most a 351 can be bored to? And are there pros and cons between a 302 vs a 351?
And I remember you guys telling me a windsor is better than a Cleveland. How do I confirm someone is selling me a windsor?
So the most you want to take either stock block bore wise is 40 over . The cyl walls become to thin after that and you run into over heat issues and possible cracking in the walls .
A stock 302 block is a time bomb after 550 whp . Depending on the tune up some guys make more etc but it isn’t some concrete number . Concenus is they start to rattle the crank esp If you have any detonation or spinning the engine some high rpm and crack right up through the cam journal .
So if you are starting from scratch what’s the long term goal power goal ? If the plan is a fully freshened engine the 351 is a no brainer . If you’re just looking for a heads cam intake car that’s a 300 hp cruiser with the intent to never really turn it up to its limit then a 302 maybe out of explorer or something with good heads on it and a good cam would be easier on the pocket .
351 for power ? Let’s just say we have a stock 79 block and crank , je piston 30 over , good rods and a 78 mm turbo that’s been 8.52 at 157 in the 1/4 and together for 8 years .
Starting from scratch on the 351 youd need an oil pan , dist , matching upper and lower intake , headers , and 28 oz flywheel before even touching the motor . Also hood clearance . Can’t remember as I’m writing if you have a Stock hood or not but Guys Have used vert mounts and k member spacers and it has beem done under one .
You cannot plan the engine build until you decide your final goal power wise .
After you did that then you need to sit and make sure the chassis , suspension and every part In the drivetrain will not be a weak link . Building cars is fun isn’t it ?
Thanks for all the insite. Based on what you told me and some other research I've done I think I'm going to stick with my 302 block and build that. Mainly because my budget, I didnt realize building a 351 could get so pricey. I would like to make around 400hp. So maybe I'll get it bored to a 331 or 347, I saw some kits for those too. My last thing that i have to decide is whether i want to turbo it. What's your opinion on should I just build it N/A or single turbo?
I read on forums that 351w can be built with a lower budget. I got mine from a 1994 F-150 and had it bored 40 over after i dropped it off in a machine shop. I forgot to mention I brought this on myself because I bought a lot of new parts like AFR heads, trickflow intake and whatnot. Also, other stuff like TKO600 and associated stuff like stiffler crossmember, new aluminum driveshaft, rebuilt rear end and dropped in a 3.73. The car needed alot of work at the time.
Only a few times I wish I still have a 302 though. I think I want to go with a 347 if I ever need a new motor.
If it really matters to you...all smog parts from 302 fits except the smog crossover tube (Too short since 351e is slightly wider). I just got a 1994 F-150 351w smog crossover and screwed on the check valve that fits, then route a 3/4" hose to the diverter valve... probably not the correct route but functionally it's the same haha.
I last saw LMR was selling an On 3 turbo kit for 1.6k:
Fox Body On3 Turbo Kit (86-93) | 302 Turbo Kit - LMR
This Fox Body On3 Turbo kit will give your pony more power. Shop our 1986-93 Mustang 302 turbo kit today for fast, free shipping.lmr.com
Also got a video on the website about the installation. One thing about that... if you ever move to CA, it doesn't have CARB EO.
I was hungry for power until this lately I thought to myself... do I really need all that power even though it'll be rare for me to even race (Yeah... why did I even do the 351w swap). Also $6k for SC is a hard one to swallow for now.
