i have been lookin into some stroker kits for the 454 motors. i like the world balanced rotating assemblies. i want to do a 496 kit. i also have been reading about the flatlander kits. 1 of my biggest questions is can i buy a kit from summit or do i need marine parts? also what other parts do i need to change to stroke my motor oil pan,pump,fuel pump ect... i already have a set of merlin ported ovals right now. thanks

I built one this year and love it. Had no problems at all. My machine shop did all the balancing. Had to turn the crank to get the correct clearence. They also notched the block. Fuel pump has nothing to do with the rotating assembly. I used the original oil pan with no problems.

what parts did you buy? how big did you go. i would like to buy the whole ass. with a new forged crank. that def. makes me want to look into it more if you have had such good luck with it.

I just finished my 496 a few months ago and now have about 20hrs on it and I LOVE it!!!! Very little clearancing on the block needed and I used my stock merc oil pan also. Believe it or not I am even using the stock sea pump driven mechanical fuel pump with only a couple of mods made to it. There are many experienced builders on this forum that will come to your rescue if you give them a day or two. I used Competition Products in Oshkosh WI for nearly all of my parts. Erik was very knowledgeable, courteous, and most of all patient with my endless questions every time I spoke with him. Continue the 496 build, you will not be sorry!!!!!!!

i am still learning about all this stuff so i need all the help i can get.

I just built a pair of Gen IV strokers this year for my Fountain. I couldn't be happier. These things make great power and have some of the best normally aspirated mid range I've ever felt.

We used the Eagle rotating assemblies with forged cranks(around $2400?) and J&E 10.4:1 pistons. They run just fine on pump gas but I've been running a blend. With the cost of pump gas in CA it's a push. I used the Merlin Dart raised exhaust port heads and they really do flow nice. Peak torque comes in at about 3100 and rolls off nice and smooth.

The strokers have a nice deep sound to them like nothing else.

What Gen are your blocks? It will make a difference on how much you spend on machining. Gen IVs' require little for a stroker kit.

my motors are mark IV blocks and i plan on going to a 496. how big did you go to?

496. Go with the Eagle rotating assemblies. I would suggest you get everything balanced. Eagle's not all that "On" with the balancing. The Gen IV blocks are a great canidate for the stroker kit. You'll be happy with it for sure. Good luck and let me know if you want mnore 411 on what I did to mine.

I also purchased my kit from Competition Products. They have many compression ratio's available. Don't skimp $$ go with forged pistons. Remember the 496 is bored .060. You only want bore .030 if you can. This will still give you 489 Cubes. If something goes wrong, hopefully you still can bore the block one more time out to .060. I had 10 hours on my non stroked engine this spring that was already bored .030. Crank was toast and I had room to bore out to .060, that how I ended up with a 496 stroker, the hard way $$$$

Anybody want to break down the costs for us?
