351 Stroker musings

[svopaul]

I haven't paid much attention or researched here like I have with the 5.0 based strokers over the years....but...I am wondering...like the issues that go along with 347 vs. 331 in longevity/durability etc. Does anyone have any insight or info like this when it comes to the 351 stroker combinations?

ci. bore stroke
351 4.00 3.50
357 4.03 3.50
377 4.03 3.70
383 4.03 3.75
393 4.03 3.85
408 4.03 4.00
418 4.03 4.10
427 4.03 4.17

I'd like to go with the 427 but want daily driver type material that I can take cross country and put a ton of miles on....so if that won't stand up to what I want I'll opt for something different but would really like to go that route.

Same rules apply. The longer the rod with shorter stroke will yield the most robust design.

Isnt the durability issue caused by the extreme rod to piston angle? I dont know the tech term for this :D

Rod ratio.

However, the efficiency of the motor will drop. :yup:

[svopaul]

What I basically want to avoid is any potential oiling issues like the early 347's had. Stroking a 351 isn't nearly as popular as the 302 so I'd just like to find some feedback somewhere on them.

I don't "need" the 427 but I'd like it for the overall presentation of the package I am putting together if I go this route ;)

427 cid just sounds too cool to pass up, especially for a small block!
:metal:

I personnaly do not know the answer to your question, but I will ask the engine builder that we have used in Illinois next time I talk to him.

He does a real lot of Historic / Vintage small block Fords, and most are 351 based strokers.

[svopaul]

That would be great input Craig....considering this is for a vintage Ford ;)


Here is what I am thinking....I am building the '67 into a Shelby clone(NOT ELEANOR!!!!)...it will be the original Dark Moss Green with white stripes....originally I was going to do a GT 350 but now I am thinking of going with the GT 500 stripes and using the 427 stroker based off the 351W block. This will keep the front end lighter than a big block. It's a restomod...but the ring of a 427 stroker is what is attractive :D

[96GTS]

(NOT ELEANOR!!!!)
THANK YOU!!!!! :jumpjacls

I think the eleanor is as ugly as sin and the regular shelbys look soooo much better :drool:

Dark moss? :think: Is that like the Dark highland green or the old british racing green? If its what I'm thinking, it will looks georgeous w/ white stripes... :drool: what wheels?

[svopaul]

The ONLY things IMO that make the Eleanor car look good is the color combo and the wheels...that's it!

This is the wheel I have in mind right now but that may change...Newstalgia wheel has them and I want 17's. The other wheel option is the original Magstar but billet in a 17"...someone just came out with that one.

Yes, the Dark Moss is the '67 version of Dark Highland Green...this car was originally Dark Moss with saddle interior...I will change the interior to black more than likely.

This is a pic of the same color car.....I am also going to run the inboard lights in the grill :D

Paul,

I just spoke with Ray at R&R Motorsports (618-438-3903) and he has said that he has never had any problem with the 351 Windsor based strokers.

He has built a few that are running around with 12-15k miles on them and have not had any problems.

He told me the one good thing is that with the taller block, you don't always put the piston pin deep inside of the piston past the oiling rings. He had said this was one of the down falls on the early 347 strokers until good designed pistons for those strokers came out.

Ray builds a lot of vintage racing stuff (re a lot of high dollar) so I trust his opinions, plus he has been a friend for a good number of years now. He is also the person who built my brothers 432 Dart aluminum stroker motor that I posted pics of.

[svopaul]

Thanks Craig....that's exactly the kind of feedback I needed. Looks like 427 :banana:

[qkjuicedpony]

do it man.i like the workmanship and the quality of all the parts i have in my 351w combo.i hope to get mine finished up in the next few weeks

[NightHawk756]

I agree with the thought of the GT500. I'm like Paul. A 427 just belongs in those cars. If it were me and I was building a clone, the idea of building a GT500 just tickles my nut hair more than a GT350!! :metal:

Nice choice on wheels by the way Paul! ;)

[svopaul]

427 it is....talked to my dist today and all the parts are no problem....H beam rods, 4340 forged crank.....I am not ready to build it yet but will pick up pieces here and there and just assembly the parts first...

[TheJeanyus]

:metal: I'm off on Fridays - I wanna help!

[svopaul]

Stop by if you like...With things being moved around here and getting more settled we will be building a few engines in the near future. 2 331's and depending when my limited budget allows the 427. I need to put a couple of basic 5.0's together as well.

[TheJeanyus]

Cool. I have lab at 5:00, but am otherwise free on Fridays as long as homework doesn't start stacking up.

[NightHawk756]

Me, me, me, me....I want to help too!! :jester:

Sweet, I have been looking at cost of rebuild kits as well, you got a really cheap 5.0 block around :jester:

I have at least 12 5.0 HO cores around ;)

:hmm:

PM me a price for a block. :nice:

[svopaul]

SCHWEET....Just got my prices.....I can get the complete kit to do the 427(SRP pistons, rings, H beam rods, 4340 Forged crank) which would be 9.3 compression with a 64cc head unbalanced for $1543 and balanced for $1679......Thats for Eagle rods and crank :D

Now to sell off this Mark VII to pay for it....:D

Cool deal, I will give you a call here in a little while.

By the way is Probe a good brand for forged pistons?

[96GTS]

How much power do you plan on?

I was out picking up supplies at Lowes if you tried to call...back now ;).

Probe is a good piston....they are made for Probe by Speed Pro ;). I have a set of Probe pistons on the way here now for a 331 we are building.

How much power do you plan on?

Whatever it makes :D.....I don't know really....I'd like to see somewhere between 350-400 at the wheels but if it makes more great and If I'm not happy with what it does make I'll put a turbo on it and already have the best parts in the engine to not have to worry about it. I don't want a race car...just a driver with plenty of grunt.

[96GTS]

I was asking Joker in regards to his Probe inquiry :)

I wouldn't trust probe slugs if you want to eclipse the 400rwhp mark.

[joker]

How much power do you plan on?
Im am not sure yet, I am still trying to decide which combo to go with n/a, then it will either get charged or sprayed. I think a good, conservative estimate would be 400-450 charged, and 450-500 sprayed. I would really like to see around 300 or so n/a, possibly more. I will most likely go charged though due to the high cost of getting the bottle refilled every time I want to go to the track. However, if it is possible to get enough hp and torque on motor alone, I may just leave it n/a. Everything is still up in the air right now, I was just asking about the pistons becuae I saw a forged rotating assembly that included probe forged pistons and I wasnt sure how good they were compared to the forged pistons dss includes in thier packages.

They are essentially Speed Pro since they make them....and we had a set make 507 to the wheels with no trouble :shrug:....maybe the weedeater versions are bad :poke:
