best stroker or swap?

[cirinoec69]

is 331 stroker or 347 stroker or building fuel injected 351 maybe stroked. cheapest and best reliabilty $4000 grand off spending cash

[draggin50]

I know where there is a 347 that I had with Trick Flow heads low comp, set up for a blower complete for $3500 And complete as unhooked and pulled out of the car. It was in my blue Gould car. I bought it from Mike. Made 341hp and 381tq to the wheels.

[big cheif]

My thinking is there is no replacement for displacement!!!:bigthumb

[03z06vette]

flaming87lx has a 351 almost ready to drop in. put some bad azz heads on it and role!!

[5.0calypso93lx]

I don't get why anyone would do a 302 based stroker when you're going to replace most of the parts anyway that you would if you swapped in a 351. You get the better block, more cubes and the potential to really make some power if you stroke it. You can easily lose the weight back off with aluminum heads and tubular front suspension.

I'd keep an eye out for a longblock if you have a $4k budget.

I had mine built and after seeing Rob's motor on here go for just a tad more than what I have in my stock block non stroker motor, I wish I would have just saved up and kept an eye out for a deal.

[cirinoec69]

guess ill be lookin for a 351 can u get enough outta the 351 with just heads on it and can it be fuel injected

[smytty]

5.0 i agree
Ashame the block is what keeps these motors tame...

Cir for 4k you can get real close to a good SHP Dart block built motor that way if you ever decide to go above 500 youll have no issues..
Just something to keep in mind...

[draggin50]

Rob`s motor is the way to go! Just sell that coupe and pick up his shortblock and build it!

[facemelter71]

Yes on both questions. Its an all around better way to spend your money. Holds up to way more horsepower and can be made almost as cheap.And yes,it can be made fuel injected.Im pretty sure 86 (not canadian) trucks with 351's were fuel injected.

[cirinoec69]

ok cool id be looking for any roller 351 let me know if anyone has one and notch needs sold it aint movin im open on price

You can do it that way or you can look for a 69-74 block which is a thicker block and are supposed to be stronger. I've never seen any direct testing but the older blocks are visually thicker in the mains. The 69-70 blocks are the 9.48" deck height so that may cause alignment issues between the heads and intake when you bolt them on. I've also heard that 73 and 74 blocks are the weakest of the 69-74 but who knows.

I run a 71' 351w block that is fuel injected and I'm using a roller cam with the retro link bar lifters. Based on the information I had heard, I limited my search to 71 or 72 blocks. But again, I've never seen any real data supporting anything besides the 69-70 blocks being shorter.

[smytty]

You can also get a Dart based stroker motor for around your price range, that way if you ever wanted to go more hp the block is there...

[big cheif]

I have a c9oe matching# 351 4-bbl motor. muscle mustangs & fast fords said the early blocks were the strongest. I think they did a 427 kit in their build.:bigthumb

[85_SS_302_Coupe]

You'd be surprised how fast 4k gets spent on stupid little shit when building it yourself. I'd highly recommend finding a good deal on an already built engine/combo from someone you can trust isn't selling you junk and go that route. Think of "used" as "broke in".

Where, on God's green earth, can you buy a Dart 351 short block (much less good heads), for $4000?

[USMCPONY]

$4,000 budget for a reliable complete motor? Good luck. Fast, cheap, reliable. Pick two cause if u want it fast and cheap it isn't going to be reliable. If you want it reliable and fast it isn't going to be cheap. and if you want it cheap and reliable it isnt going to be fast.

[smytty]

Not a 351 based block but hell to have the dart block as comfort...
As for a 302 dart based block stoked out with all the goodies is about 4000-4300

[Timido]

$4000 budget. Find a set of used vic jr heads vic jr intake. Build a stock block 408 If you need help getting started I have a stock 79 block that has been machined .030 over and line bored. Pm me if you are interested. A cast stroker kit is all you need. Keep the rpm and timing reasonable and it will last. Spray the crap put of it with a bad tune or try to turn 8000 with a stock block you will kill it. You will have to search for used parts and build it yourself but it can be done. $6000 might build you a dart shortblock.

[RIXXX93GT]

If I was starting from scratch I would look for a stroked 351...408. Probably with a solid roller cam and carb.. If its a daily driver then maybe the EFI route.

This will probably be your best "bang for the buck" route. Should have no problems getting into the low 10 second range.

[Rick93coupe]

Stock block 408 with decent heads is where it's at. Walk the line on compression for pump gas and it'll be bad ass. Be careful of used heads, you never know who's had their hands on them and what's been done. Sometimes it seems like a great deal but you end up putting enough money in them to have purchased a new set that were cnc ported.

I agree. Get some good heads, 11.5-12.25:1 compression, solid roller, long tubes and hang on.

Is the 427 kit to aggressive for street use? that is what i had planned on getting for my C90E code 351.

I think the issue comes with the crank to cam clearance on a 427. The extra long stroke causes the crank to get into the cam tunnel. I think you can run a reduced base circle cam but that can lead to a little bit of valve train stability issues.

Another option is a 418. It is a 4.10 stroke vs the 408's "4.00". You get an extra 10 cubes for basically free.

[NXcoupe]

I built a 427 stroker in a 351 roller block, one of the old sportsman 351 blocks from FRPP, and had no issues with cam to crank clearance. I checked it on all the journals, and it was fine. But we were running less than .600 lift. Just my experience.

[big cheif]

I might want to use the smaller kit. I think this thing has a deck height .010 smaller than later model blocks.

[cirinoec69]

might have found a complete 88 gt with a 306 that has heads might just swap engines

[jack90gt]

what is the matter with the 88gt?

[A05C]

the 69 351w blocks are a few thousandths shorter than the later blocks. I've got a 74' block'd 410w in the 12.5:1 range setup for nitrous I'll consider selling. PM me with questions/interest
