Title: V8 conversion questions
Post by: yblock64 on October 04, 2009, 07:46:25 PM
Hey V8 Guys, Could you help answer some questions? I have a 1979 trunk model that will get a 302 transplant. The following Mustang II parts will be used-oil pan&pickup, engine mounts(new old stock)& brackets, C4 With 141 tooth flexplate, small bellhousing, torque converter and block plate, Hedman Mustang II headers, 8" rear axle. I'm hoping to get the V8 into the engine bay without cutting the support at the top of the radiator, is this possible? I've heard the headers will require modifications? Electric fan will be used, should I go with the Ford Racing short water pump? What about pulley alignmant issues with it? Using a Wieand Action Plus low rise dual plane intake, will I be able to use a stock hood with no scoop? For now the engine will be a 1976 302 from a Mustang II(I know only 134 H.P.)for mock up and sorting out other issues. The only performance items at this time will be a Motorsport A311 cam, same specs as the Edelbrock performer, headers, Wieand intake with Autolite 4100 4bbl 465 cfm. RPM range will be 5000 max. Transgo shift kit, 2.79 or 3.00 gear(I do have a 3.55 trac lock for later). I just want a good fun driver, not a race car. Given the info here, do you think this combination would be good for low 15/high 14 second 1/4 mile and 20 mpg? And lastly, what do you think this combination would weigh? Thanks for your advice.

YB64 you shouldnt have to cut the core support at all. I have a 71 trunk model with the smaller engine bay and still have my core support. 71pintoracer has a great thread for the install on the early pinto but yours should fit in with less fabrication. If you need a short water pump i have a new ford motorcraft short pump high performance with standard rotation that i would sell cheap. Good luck with swap. v8 pintos BIG fun.

smallfryefarm-
Thanks for your reply. I'm glad that the support can remain intact. My goal is to build this car similar to the way Ford would have built it back then, but without the smog junk. I might even use the Mustang II exhaust manifolds instead of the headers- what do you think? Any ideas for the radiator and placement? Compared to your experience with your V8 Pinto, do you think my performance goals are realistic? Lastly, the short water pump you have, do you have a part# for it and what is the price? Again, Thanks for your info on this subject- I'm trying to do my homework to avoid headaches.

Im just not familiar with the room you have in the late model pinto but i know you have a lot more than i did. I put the radiator on the outside of the core support but im not sure you will need to do this but if you plan on doing that then you should have plenty of room for the regular waterpump. I will get the # off of it for you in case you need it. i would take 75,00 and i would pay the shipping. But you probably wont need it. Unless you are going to build the motor i would try the mustang II manifolds and save the money. Search the site use the search field their are a lot of late model v8 projects on here and you can see what they did. I am pretty sure you have the easiest car for the swap. good idea do a lot of research good thing is all the data is rite here on this site and soon im sure you will start getting response from others who have done this with your car. And YES the pinto will run great with even a stock v8 i mean Great. any way good luck with the build take lots of pics and post them for us and keep asking ?s and you will get the answers like i say plenty other late model v8s here. just plan on not cutting the core and plan your build accordingly.

smallfryefarm-
Thanks for the feedback. I'm thinking of a custom aluminum radiator with a remote fill cap spliced into the upper hose. That should allow me to tuck the radiator under the core support if needed. I think the Mustang II manifolds would be much easier, but I do have a brand new set of Hedman headers just in case. Yes, I'm interested in the water pump when you can get the part#, and the price sounds good. I wanted to replace the iron one on the 302 anyway to save a few pounds, and having the extra space at the radiator couldn't hurt. It has been my experience that Ford guys are a helpful bunch. Thanks

I bought a griffen radiator and put it in front of the core and notched out the core for the cap. 71pintoracer did this on his thread called let the fun begin. Which is extremly informative on v8 install on the early model pinto. but it would be worth your time to look at it and check out the radiator install. i will be at the shop this evening and get the pump # for you.

Yes, I saw the rad. install on 71's pinto- looks clean. I'm hoping I won't have to notch my support, but if I do at least I'll see how to do it right. Thanks and I'll look forward to the water pump info.

Motorcraft M-8501-E351 High Performance water pump. Its a short pump made for v belts and standard rotation. First thing to do is find you a water pump and crank pulley that will work with this pump before you decide to buy it. I put it on my car and tried to find a pulley set in the junk yard but didnt have one. So ordered a new set of custom aluminum pulleys from ford motorsports for a short water pump. But they were off a quarter inch. I told the people at fms and they sent me a new pump to try and it worked thats when i discovered that i had a motorcraft pump and thought it was a ford motorsports. any way i ended up with a extra pump brand new was installed but never started. But dont buy it till you find a set of pulleys. Its actually 1/4 shorter than the fms pump other than that they look identical.

just let me know either way no hurry its just sitting here,

thanks David

Thanks for that info. I did not know that there were two different lengths short pumps for the small block Ford. I'll research the pulleys and let you know. The part # I saw in the Ford Racing site was the same # as the one that you have(M8501-E351) except their # has a "S" at the end. The description is street rod, short- standard rotation, v-belt.

Ah Haa! Ford made it a bit complicated didn't they? Oh well, I guess I'll start digging around the junk yards an in the parts books. Thanks for making me aware of the alignment issues, a non-Pinto person would have just sold me something without telling me. If I can get the correct pulleys I'll still buy it from you. Oh well, that's what makes this engine swapping fun, huh?
      Thanks, Richard (yblock64)

A different, slightly more exotic water pump possibility can be found from Snow White, a company which specializes in street rod parts.  They have a setup which uses an adaptor to put a waterpump from an Opel 1900 on a SBF.  It's the shortest possible setup and I've got it on mine.  It works pretty well...

Thanks for the info. Interesting set-up, that pump....I did want to remain all Ford in appearance, but as I progress I'm sure open to suggestions-after all, you guys have already done the V8 thing and know what works. I'd really love to hear about the members cars and how they perform with the V8. Thanks, Richard
