Default 1989 Mustang GT looking at a 408 stroker

Hello

I sent another thread but it didn't post so I'll try again. I am looking at a motor from blueprint engines and this seemed to be a pretty good deal. I spoke to comp cams about potentially changing the cam in this built motor to squeeze some more power out of it, but he suggested that the cam in it with the heads that are on this engine are pretty good for streetability. I've attached the motor link below and I wanted some opinions..or suggestions.

Cheers

For the love of God...BUY IT!
Go on youtube and search 408 stangs. They are all fast as $%#& and beat whatever they are up against 95% of the time. 408 is one of my dream motors to put in my car.

That is a very mild mild build.

Plus how can the guy at Comp Cams tell you that as there is no information on those heads.

Not much info on that motor.

it's nothing great...you could stroke the motor you have with top end parts/heads and make more power...also you need alot of supporting mods and other parts to swap in a 351
Also how is your transmission, suspension, brakes and fuel system? If they are stock...hee hee, bend over, you get to replace all that too and more...talk to someone who builds/tunes cars and make sure you know what you are leaping into

True that. Shattered transmissions and rubber coated streets all day everyday

^^Good advice here. Good suspension, brakes, tires, and drivetrain often make the difference between a stroked-Stang being an underachiever or an overachiever.

Hyper pistons and no head brand mentioned? I'm very suspicions.

Some good advise here. I'm not a rookie on engine swaps just wanted to know if anyone has done this swap before. Tranny is stock, and should hold 425hp with a better clutch. Fuel system will be totally replaced and a new tank better then just washing it out, don't want any particles going into the new motor. Suspension well that would be in the works but the suspension can be upgraded later. I'm not a racer, thats in my past. If I do go to the track it would not be often. With my other two GT's I've had I went to the strip 4 times, just to get baselines and what my mods gave me. You right though, suspension could use an upgrade and the brakes too..But in time..

However I did think about the motor and getting it worked on, no mods with fit in the engine bay!!!But is there any retro fitting in putting in a 351 from a 302..

Cheers

Yes it will fit.

Might have some clearance issues with the hood, headers will be a pain and some minor things needed for the swap.

I read an article on the swap and it seems pretty straight forward and your right a hood will need to be done.

Is there anyone that has a 408 they have swapped that could give me some advice???

Its funny, so may options to choose from. 331 to 406 and greater in CID, but I really don't know which way to go. If I do go for the 347ci, then I can add exhaust and other stuff to my 302 this year and work on a 347 as the monry rolls in..It should hook up and maybe add heads that I can swap to a 347 later...

Best way to do it would be just to save money till your ready cause if you try piecing things together things change. Also 302 items are not optimal for 347 breathing. So swapping your 302 stuff onto a healthy 347 will not net you the best results.

I think thats a good call, I'll just focus on the car and making it clean and TLC'd, do the wheels and other fun stuff like gears and exhaust for now...Motor when I'm ready, or when a bonus check comes in LOL
