460 550hp
hello i have a 460 from a 75 mercury marquis and it is in a 75 1/2 ton.
im looking at dooing up tha motor a bit. it has good compression (135) and i was looking at the edelbrock powerpackedge it claims to put over 500 hp on a 460 with heads, headers, cam, intake, and carb. can i get more hp using different companies? better heads, headers, cam, intake, and carb? looking to do a cheap build that wil fire my truck down the 1/4 mile.

short answer- yes you can get more than 550 horse building it yourself, it all depends on how much money youre willing to put into your build, and how much you can do yourself as opposed to paying someone else to do it. if you had, say, 6000 dollars to put into the build you could build a nice 521 stroker and still be able to run pump gas... but since you said 1/4 mile- nothing you can do to a truck will let it be a good 1/4 mile machine... its just too heavy. best youre really going to do is maybe a 12 second 1/4 and thats if you build everything as good as you can and spend 12000 dollars or so on the parts

my 2 cent's i like edelbrock intakes but as far as the carb's and heads i wouldnt bother with them from what little i know is that alum heads are a good start and trick flow makes a good alum head and i have heard that the jon kasse scj alum heads are suppose to be the best out of the box street head you can get and i hope so since i just picked up a set but anhow i would look into a good holley carb maybe even a domanator of atleast a 850 double but if you want to build a good 1/4 mile motor be preparded to spend some cash you can get a good stroker kit for arouind 1300-1800 that combined with a good mach shop roller cam /lifters a good set of headers you should have a great start and as fat as the truck goes it isnt the best 1/4 dragster to start with but first thing i would do is gut the box and interior lighteen it up as much as you can with out sacerficeing stringht some sticky tires and you should be able to run just fine

i can get good deals on big name brand parts so i was thinking of trick flow heads but the a460 you have to have different pistons i was kind of wanting to keep the bottom end mainly stock are the 460 trick flow good or should i do like a ford racing scj head? i guess im not to concerned about the $$ cuz there is no sense cheeping out. i have seen a couple trucks break the 12s with some minor mods and 150hp nos. i don't want to be any faster than 11.5sec all motor so when i crack the bottle she will fly, ps i live in Saskatchewan so i don't care about emissions although i does have to run 91 octane fuel as far as cam goes should i phone a tech line or pick one which i think would best sute my build?

if it were me and keeping the shortblock stock id probably go scj's and call a cam company about a cam... but i wouldnt use stock pistons and nos... youre just asking for trouble... also with the nos and and an already pretty warmed-over top end id start to worry about the crank... 800 horse is max on a stock crank... so if you want to put a 5500 lb truck to 12 seconds and hit nos on top of that youre looking at 850+ horse and for that id go forged crank

also with the Kaase designed heads (either the FRPP SCJ version or the new ones Jon is coming out with now) need different pistons than stock.
The A460 heads are a race head, or at min max effort street/strip head, remember during the 80s they were basically the prostock heads. And not only do you need different pistons but they also require different intake and exhaust manifolds as well, plus different head studs, pushrods, and head gaskets than the stock style heads either alum or iron.

If your 75 1/2 ton with a built 460 cant run 12's easily then somethings wrong! I cant beleive that it would take 850+ to get that brick into the 12's!!! There is a guy in the FE threads that is running a 410 that runs well into the mid 12"s with a 65-66 bodied full truck! Do your home work and you will be SUPRIZED!

he said he wanted it in the low 12s to high 11s without nos... after nos low 11s high 10's... thats where the 850+ hp comes in

Lance to give you an idea, there is a guy on another forum running a 79 bronco that runs in the mid 10s last I heard, and it's taken him awhile to get there. Pat runs a 598cid A headed engine solid roller cam, race gas only motor, I don't remember the exact HP on it but I am pretty sure he is pushing 1000hp to get it done. Yes it really does take that type of hp to get a full size truck into those numbers. Another example my dad runs a 76 1/2ton chevy (yeah I know I can't get him converted) short box 2wd with a 454 that dynoed just short of 500hp and he is in the 14s

you need differnt pistons than stock for the frpp heads? flat top's work with the heads that is what was running in the motor the heads came off so why wont the stock dish pistons work? and as far as getting a 460 into the low 12's isnt very hard but my opion is befor you spend money on alum heads or any top end parts you need a good solid bottom end a stock crank will work fine that is all i ran for 3yrs and it twisted close to 8000 rpms but i did some priceing and a stroker kit isnt to pricey i picked up a scatt 500 stroker kit for around 1,100 and that was my pistond rods and cast steel crank you can get a bigger stroker kit for not much more the olny reason i went with a small stroker kit is due to cid rules in my class but if you dont have a cid rule than go big you can get a 557 kit for under 2g

i have hear that the frpp heads are a great head and i hope so i also saw a set that were cnc ported and the motor was said to be pushing 1000+hp if that was naturaly asprated or not? but anyhow why did thease heads work with flat tops the motor thease heads came off were kb flat tops and he didnt cut the pistons i am gonna clay them tomorro and see what my clearinces are and if i need to cut them that is ok i am just confused why they seemed to work just fine befor but my pistons are differnt so maybe i will need to
