Howdy,
I have a 1966 Mustang with a 200ci and a three speed manual. I want to drop a bigger motor into the car. Preferably a 302. I talked to a mechanic and he said that I can probably pick up a 302 with a tranny, a correct length drive shaft for about $500. Is there anything else that is needed for the conversion. Some people have told me that I need to convert the wheels to five lug and that I will need a whole new front end. What is true and if anyone has done this I was wondering if you could send me some info.
Also is there a particular 302 that should be used (What year and Carb or Fuel Injected).

 

I can't say for shure on the 66 but the 200 CID I6 made it into the fox stang until I think 82or 83 and the K-MEMBER IS NOT compad with the one used for the V-8

I have done a coupple I4 to V8 swaps and the EFI is better for a mild combo or close to stock . But the carb is the easyest and cheapest way to go . you cot a lot of work to do and the EFI just makes more of it . stay with the older block and heads they make more power and have bigger valves and higher compression (pre 1971) .

 

you want to get a pre 69 302 mexican block with brodix heads. that will make over 300 hp. and stay carbed, it is easier to put in, less wiring and shiz

 

heay matthockey32 do you got cast #'s to tell if you got a mexican block

 

thats the Boss engine. it had 4v cleveland heads on it from factory and revved to 8500 rpms. totally kick ***

 

You stick that Boss motor (will not fit anyway) in that 66 or a strong 302 in a 6 banger car, and you’re looking to strip off the lug nuts in a race.
All wheels need to be converted to a 5 bolt pattern and upgrade the breaks and suspension.
It is much easer to either:
1) Performance enhancing the I6 will bring the HP up to a stock 289 2V
or 2) start with a former V8 body.

The Boss/Cleland motors are to big for the 65/66 cars, but a 351W works.

the Boss 302 was a 302 mexican block fitted with different heads. it will fit but you need a strong tranny

 

Clifford proformance is whare to go for the parts to hop up the 200 , I did my 300 I6 from them and It respondet to the up grades very well . Was most impressed with the resluts

 

Yes, the front suspension has to be upgraded to handle the extra weight.

 

what is the wight diffrence , how mutch could it be ihe I6 is real heavy remeber the blocks are hallow inside so looks could be deciving . my fox stang is a ornigal I4 and has the I4 springs with the small block . It dose not squat or handle like a POS . I dunno .

Is the k-member compad between the V-8 & I-6 in 1966
