GT5088

Hi Guys,
In a few weeks I am pulling the motor out of my mustang for the winter to freshen up the motor and modify my motor as far as my paychecks allow me to...any suggestions on where I should get a stroker kit? Also any other suggestions on what else I should do while I have the motor on the stand would be appreciated...Thanks!

Isn't a 5.3L a 327, not a 305?

GT5088

idk...I was always under the impression it was a 305....I know the 4.8 is under 300 ci...

Valentino

61 cubic inches for every liter...

but back to your question, if you're going to pull the whole motor apart and do a stroker kit, you might as well go all out and replace everything else with aftermarket goodies. I'm not sure where you should buy the stroker kit but I think DSS makes some good kits, or try thumbing through the ads of MM&FF or 5.0 magazine, I always see lots of stroker kits advertised in them.

GT5088

then I have been wronged....

GT5088

but back to the original point of this thread....I get MM&FF and 5.0 every month, and they have had a few articles involving the D.S.S kit that is roughly $900....there are kits that are lesser and more expensive.

I know alot of people on here have stroked their motors, and just wanted to know if anyone had any particular experience, good or bad, with any particular brand....or any recommendations..

Thanks!

What kind of horsepower do you want to make?
Is it still going to be street driven?
Are you going to run boost or stay N/A?

GT5088

well I would like to stay naturally aspirated, but I don't drive it on the street too much, maybe one or two nights a week, so its not too much of a factor... I just want to do this right the first time, and not waste money on lesser expensive and lesser quality parts...

Just remember that you get what you pay for. I prefer 331 myself but that's my personal preference. I use Eagle H beam rods and Probe pistons...not the cheapest out there but again...you get what you pay for.

GT5088

Thanks for the advice. I want to use good materials, even if it costs a little more...is there any advantage going to a 331 kit over a 347?

svopaul

A 331 has more longevity than a 347...you can get over 100K out of a 331 but not with a 347...at about 70K roughly you will need to freshen it up.

GT5088

yeah, then it looks like the 331 is the better option....is there anything else that youd suggest to do while i have the motor out for the winter? I'm open to any and all suggestions...

Well 331 or 347 which ever one that go with. I (personally) woulndt go with a kit... I was always told going fast isnt cheap. If you are wanting to go fast get the good stuff. In feb. I am buying the DSS 347 stroker short block ( that is the entire bottom end minus the cam) Then I will take my heads, cam, and intake I already have and add it to it. When you reuse your stock block and bore .30 over and then use the kit, yeah it might run good BUT remember it is the stock block and once over 500 hp they can (might, might not) split. I mean why risk it do it right the first time. Just my opinion......

347strokin

I would run a main girdle to help strengthen the block. And my preference would be to build a motor that doesn't rev to the moon. Torque is the ultimate on the street. You don't sound like you plan on building a 500 h.p. motor so I wouldn't worry too much about splitting blocks.
You will want to save some cash for some better heads as well.(Edelbrock, Trick Flow etc.)
Get a good forged crank (Eagle, SCAT), H beam connecting rods, and good pistons depending on your application and you'll be laughing. Just spend some time/research on your cam selection and you will have a nice street beast.

GT5088

thanks for the advice! Me and my buddy are pulling the motor soon and I want to get right on this..and do it right

bob

Well if your going with a 331, not much to say, but when the 347 was under consideration , I was gonna say, dont worry to much about rod length, longer is better, but with a street 347 you want a piston pin thats below the oil control ring and doesn't require a spacer to support the oil control ring.

GT5088

yeah, I pretty much have decided on the 331 kit from DSS...we shall see what the results are come spring
