So I read some people say to mod my current 6 cyl and it should perform like a v8....


Ao this leads me to my question....should I mod the 6 or I was thinking of getting a 351 or a 302 (would like a boss) and throw that in??

My thoughs are to make this a street legal fast hot rod. possibly invest time and money. I am not afraid to get a old 302 or 351 from a junk yard and rebuild.... if thats what it takes.

also will a 302 from an 80's mustang fit up well with the current C4 tranny???

sorry for the newby questions.

 

Theres way too many V8's

why not build up that six
heres a good start

You won't reach the power of a V8 with that six unless you seriously modify it...bigtime.

Check out www.fordsix.com - those guys are great.

I also have a six cylinder, but no way can it match that 8. Now, if you bought Mike's new aluminum head, threw a turbo on it, cam change, new intake, bigger carb, you might get pretty close, but if you're not in love with the six, go with the V8 swap.

Now know that, if you swap, you're going to have to change out a lot of stuff. That's been covered though, so I'll let someone else post the specifics of that, if you go that route.

 

if you use a v8 you gotta change rear ends front spindles and brakes springs shocks engine brackets and mounts tranny cross member

 

IMOthe I-6 that was put into the early Mustangswill never aproach the power of a V-8 for a dollar for dollar investment in performance parts.

This said, the conversion you are speaking of can be expensive as well, I know because I am doing it now. We did not aproach our conversion with economy in mind, and we have spent some $$. IMO the conversion is economicly viable if your six cylinder car is in good shape body and rust wise. If you have rust or serious body issues a conversion is not really viable unless your car holds special sentimental significance to you.

Your engine (of course), transmission, rear axle, and other parts (throttle linkage etc.) will need to be replaced. If your Mustang is a 64 - 66 many front suspension/steering components (spindles, brakes, etc.)will need to be replaced.

If you have access to a donor car that has good components (transmission, rear axle, steering stuff, brackets, etc, I think that the conversion could be done for $2,500 to $4,000+ the price of the engine.

Going new will cost (much) more.

There is nothing hard about the swap, it is strictly a bolt in affair, and a good rust free body will save you mucho $$ and timethat can be applied to the cost of the swap.

 

Do the swap for real horse power, as most here know I work for a crate engine builder and I also have made the swap from I6 to V8. Its not hard but can get expensive start with the power range you want and then consider what effect that power will have on related parts like trans and rearend. here is the link to where I work for example of power potental but you can stil get more power that whats rated by upgrading. http://tandlengines.com/

 

i have hot rodded my six and im gonna put it to you like this

most people want the 5-lug for better wheel selection so you may want to convert to a 5-lug and if you wanna modify you six to get alot of power you are gonna need a new rear end and trans. so basically you will be doing everything you would have to to do a v8 swap so im gonna say this if you are not in love with an I6 dont keep it cause you will most likely do most everything you would need for a v8 swap minus the motor anyways so if you are unsure about whether or not to do the swap i would say start doing the basic things like a 5-lug swap and rear end and brakes then when you get farther down the road you will be ready for which ever you decide on

 

If you hot rod the 6 cyl. ,you will be a one in a million kind of thing. Sounds like a real cool idea,why not be different? I bet you would get as many or even more ppl staring at your engine at a car show,especially if you do something really nasty,like a turbo or NOS or both?

 

i too have a in6 with a 3 speed i'm not happy with it and i want to dumpa 302 with a 5 speed in. my question is my car is already 5 lug so could some one tell me what that means?

 

Somebody modified you car. Either they did a five lug upgrade, perhaps for a granada disk brake upgrade and changed the rear end to match, or they put an I6 into a V8 car. What is the engine code on your door tag (windshield tag for 68 and newer)? T = 6: A, C, D, K, S = V8 Other codes may apply depending on the year of your car.
