Thread: Another 454 question

Tweet

Was curious what would anyone recomend as a maximum stroker kit and bore for a 1974 454 2-bolt motor with 781 heads with an automatic trans and ford 9" 350-1 and how much horse /tork could you expect and would there be big gains with aluminum heads just checking options with so many kits on the market.

PM Pat Mccarthy.

I just balanced a 4.250 scat forged steel crank this afternoon---its fo a 540 dart block-- balanced fully internal at a bob weight of 2302 grams--

I have run standard bbc as far out as .125 over and if 2 bolt block would at least use studs for the mains

i built the mark four 454 two bolt with a 4.320 bore with a 4.375 crank with a 6.385. rod .i done many.many 4.250 cranks from 496 to 568 i have 4 going on right now two scat cast steel cranks with Gm thumb rods with ARP bolts. and two 4340 scat cranks with 6.385 I beam rods will be going for sale soon .two bolt mains can hold alot of power . i do not buy kits .i make up kits of parts i like to use. how much power ?? thats a very open question no limit on money or CR ? start getting past 700+hp then the parts change for better pistons and rods and would be looking to stud the main and 4 bolt caps last week i did this 3 plugs

BigBlockT, you would do well to talk to Pat, he knows his stuff.
I don't want to hijack the thread but PAT, your PM box is full, you need to clean it up.
I need to get a transmision built for the van. O.D. or TH400. Who would you recommend I talk to about one? PM me back please.
Thanks
Mark

sorry about that mark should be room now ? or just call me on the trans FRED V is who did all my stuff most of the guys in town here he one of the best if you do the 400 there is some small things to do to make it work very good i can talk to you about that .so if you want i can make a call to fred do you have a core 400?

Thanks Pat. I'll give you a call tomorrow.
Okay... back to the 454 thread...

yes money is a factor but when you can buy a dart short block and put a pair of dart heads on it between $7000-$9000 with decent size with lots of power this motor would be going in a 2500 pound streetrod but if the car was ever sold it still would provide enough power for a hevy car or truck I thought 600-700 horse sounded cool what started all this was an ad for a new 598" dart short block for $4700 all I could think was the power and cost compared to what I was able to do with my stock 2-bolt as stated earlier Im just curious

well i can tell you the stock bbc has been used in many builds and not just buy me i can get all the dart stuff and used alot of it .but i like building the stock stuff with a 4.250 or 4.375 just for fun . when you get past $5000. in head casting and just valves . get past 4500 just for a bare alum block some of the fun wears off i machined built many hi 500s to 632 bbc just more money the 589 is really nothing new you can put a 4.500 crank in a stock 9.800 GM block if you want to as for street rods i sold my 548 14to8 748 solid roller street engine to a guy with a 2500. street rod i put it in for him car was more then one hand full
