My question was aking if you get a tubular k could you run Longtubes, I know they fit the 4.6 with the stocker, and the k members from verts to coupes are the same, the verts just have a brace that bolts to it

you talkin on a 5.4 swap? its the heads to shock tower clearance thats the problem

Oh hahaha my bad I thought you were askin if you could run longtubes on a stock K and 4.6. Wow that was my moment for the day. I understand your question now. And i think I'm just gonna stroke the 4.6 and have it slightly bored. And put me some happy gas on it

long tubes sparky, heads to shock tower clearance is the main hold bold on them not fitting.

The sets my friends made, and sent to bassani for them to copy and patent we had to cut down and get them to hug closer to the block then start going down and back

Depends on the longtubes, some require minimal modifications, some are not even worth trying.

I love stroker motors, good luck man, you'll be happy getting stroked and blown

alot of the issues iv heard with 5.4 swapped cars with longtubes were actually hieght issues. The collector was right were the floor starts

[Mustang02gt]

when weighing the options of stroking a 4.6 2v or swaping to a 5.4 2v i definately would go with the 5.4, preferably mocked after a lightning with a kb blower, so what you cant have long tubes, sell them for some cash back in the bank to invest into the 5.4. mean everyone seems to speak more of and worry about HP more, when hp typically turns to bragging rights while torque is what gets you down the strip quicker. id much prefer having a 5.4 2v cammed pretty hard shorties putting out like 386 hp and 500+ ft lbs than a stroker motor pushing 425 hp and 390-430 ft lbs of torque cause the 5.4 will end up out living the 4.6 due to the fact of it being a stroker motor

just personal opinion though . theres so many pros and cons . each has there own gains each cost a decent amount of cash to build.

I mean I have a lighting swapped car and i can tell you its much more fun then any vortech car iv ever driven

[Mustang02gt]

thats what im sayin im building my 5.4 for a lightning swap runnin blower cams from houston performance, shorties and esentially all the other bolt ons, and dunno what pulley i want yet, but if hes talkin bout stroking a 4.6 he might as well swap to 4v 4.6 stroker with a nice set of cams and some type of FI or giggle gas

you point on stroked vs 5.4 is invalid, have you seen the rod length of a 5.4, its a longer rod than a stroker 4.6 rod

[Mustang02gt]

true but your taking away material from the block weakening the 4.6 essentially the rod length is long on the 5.4 yes thats a given due to more cubes as well as it being taller block, but when you stroke a motor cutting the block to allow more clearance for a taller crank and thats before if you bore it over any. thats what my statement was about. its like saying a 302 stroked to a 347 compared to swapping into a 351, a 347 will turn higher numbers but its lifespan will be shorter than that of a 351 most likely

5.4 stroke > stroked 4.6 as far as numbers go. Yes the rods are longer and you have a greater stroke, but the rod angles arent as bad so it doesnt put as much pressure on the piston skirts. You do still have the issue of higher piston speeds, but realistically you can get away with the same RPMs as with a 4.6.

The only metal you will take off of a 4.6 with a stroker setup will be whatever oversize for the pistons. 5.0 stroker kits are about as far as you can go with a 4.6 block due to the length of the cylinders, there is no need to notch the block for the crank.
