while i had been making plans to build a 4v cleveland powered maverick, a 79 mustang maybe falling into my lap. i know that with enough creativity (and sometimes a large hammer) one can fit almost any engine into any chassis, and i have seen pix of a few cars with this combo. so my questions revolve around what others have done here for this combo (headers, motor mounts, gear ratios, k-members, suspension upgrades). obviously there are many variables, but what have you guys done that works well for a strip only car. thanks in advance

302B and 351C into a Fox platform is easy, in my book, as long as you have the headers, or can modify some. Hedman still lists the headers for the swap, and you see some on ebay and elsewhere fairly regularly. There are several members here who have Fox-body racers with Cleveland power. One is even selling his very nice and quite quick C powered Fairmont. I ran my Boss 302 in a '78 Fairmont for a while, and the normal Fox setup tricks worked very well. I just did a good C4/converter, 8.8 out of a later version, frame ties and ladder bars. Simple but very effective.
A couple of guys here have C powered Maverick type racers. Not so simple to adapt a C to that little car, but do it right and it will fly, while (arguably) looking better than a Fox car.
You will probably get some very worthwhile responses from the guys running both chassis.

i agree that when done right, a mav looks very good. i am now building cars from a wheelchair, so the availibilty of quality bolt ons for the fox body that will save on the time spent fabricating becomes a big factor. the more i look into it, the more it looks like the mustang will take less time and money to get to the track.

are those custom headers? most "off the shelf" designs bend sharply just past the mounting flange, those look like they would flow quite well

We have had 2 customers install 351C in a fox body car in the last month.
We sold them a Kevko Oil pan and Hedman headers.

I have heard good things about D&D stuff. Also Kooks Has nice headers. I had a set of Headman for the price not that nice.

Here is a set of the Hedman Headers for the 351C/ Fox body. I thought they looked pretty quality.

I have an old set of slip tubes that look like these. I always assumed they were hedman. Sadly they don't fit my Fox tbird with the 400.

Heres a couple pictures of my cleveland fox combo. I used a QA1 k-member and flaming river rack, canton oil pan, hpm solid motor mounts, and hedman headers without any issues. When i changed to chi heads, had to grind some clearance to the trans crossmember for the headers because the exhaust ports are raised a little. I also have the frame tied with a 9in rear and adjustable control arms. Car weighs 2850 with me in it. Put that cleveland in there and kick some butt! [linked image] [linked image] [linked image]

Headers

June 17 2010, 9:12 PM 

I am not a fan of the flat collector and the thin flanges. The tube gauge seems thin to me also. I have had two versions of the kooks and liked them both, two barrel and four.
87 Boss351 what kind of times are you getting with that beauty!

Not sure of brand

June 18 2010, 8:49 AM 

but Holcomb motorsports provided me with some nice hand made (welded from bends) headers that had std square collectors. Collectors slipped and each cyl flange was separate on to allow individual tubes to be installed. These put 4v heads in fox chassis.
