hello i bought a multi tool the other day so i could port my own cylinder heads. I just want to know how much i need to take off the ports into make a more efficent flow and add 30 mor cc's to the heads i think the guy said they were 160cc right now and they need to be 190cc so how much should i...

with an hi lift cam dramatically ported heads 1.6 ratio rockers and the 372 stroker kit they say at best i can make 550HP thats what the stock heads can handle ill be satisfied with 500 or even 450

something is wrong with that then because those bigger stroker kits are rated for a lot more HP and everything was pretty much stock on that the intake exhaust from that im guessing they wouldnt bother with a new cam or rocker arms sure just the kit will give you that HP but i checked with three...

i talked to a tech and im going to need to do serious porting if i want that power from the stock head there at 160cc right now i need to get them to 190cc along with a compcam xtreme hi-lift cam kit and m-1 single plane intake i should make around 550Hp with a 9.5:1 comp ratio i will need a...

i bought a highrise M-1 from mopar performance the bolt holes on the intake didnt match the stock cylinder heads i was pissed hah

its a mild cam so i should go bigger? any recommendations?

i guess you could but like others are saying you can blast the flat surfaces or the ports might wear them to thin.

its a 727 torqueflite auto im looking to get mid 500's to top of 600HP i can get whatever torque converter to compliment that. The kit with dish top pistons can reach that HP range and the comp ratio is 9.5:1 so what kind of fuel would that be needing. The purpose for the car is street/strip...

the engine is a 340 with stock x-heads. But im in Alaska it'll take a long time for the kit to get to me and if something is wrong it would take awhile for me to send it back but the kit is rated for 600HP using dish top pistons 4340 forged connector rods and a crankshaft 5140 but if i get the...

hey so instead of getting a 416 or 417 stroker like i was saying i decided to go with something a little more managable i think a 372 stroker kit. You can view the kit here(...

hahah damn thats good maybe to even get a little more some indy heads (kinda pricey) yeh usually the 408 stroker kits can withstand 500 to 1000HP depending on the crank for a simple $200 dollar upgrade can make a huge difference. You probably need a huge carb 1050 CFM maybe but everything sounds...

hey if you haven't got rid of them yet could you put up a few pictures im very interested i need a kit bad im in portland area i can pay for shipping thanks nathaniel

no power brakes when i have the engine pulled i will upgrade the brakes and control arms and most of the suspension on the car i cant remember the gears exactly 8-3/4 maybe money is not a problem im going to organize what i need then save for a year and all at once order everything and do solid...

i think one of the old 62 newports with a modern twist would be cool maybe put a hemi in it hahah

its a 71 duster 340 automatic 727 tranny dual exhaust H-code engine with X-head and with 3rd member rear. Im pulling the engine and having it bored 0.30 over and having the heads refurbished and cleaned and need to know what rocker arms i should get because im not happy with the stock ones i...

hey, so after hearing what you guys have said i've decided to go with the 416 stroker kit for my 340 instead of the 408. But now im stuck on finding an appropriate cam to compliment the stroked engine so if you guys know of any valve train kits or cam that would go great with the kit please let...

if your running a 800cfm carb your going to need an updated cam for sure to have a longer intake duration but if your going through the trouble of having the engine cleaned and bored you might as well get a stroker kit or a rebuild kit they're going to cost around the same or you can go on e bay...

you can go 4bbl just make sure its not a huge carb and intake or else your going to have to deal with updating the cams too just a simple intake mani with a 600 or 550 cfm carb will do

hello, I have a 340 in my 1971 duster im thinking about pulling the engine to rebuild it with a 408 stroker kit. But first i want to get the block cleaned and resurfaced. If i got the cylinders bored what would be the best? (.30 over??) and would the stroker kit still work if i got that done...

1971 was the year with the least produced 340 dusters so therefore they are the rarest planning to get the 408 stroker kit i love my car

you'd have to get a new intake manifold to 4 barrel set up 2 to 300 for that or you could runa weber system check it out

NOOOO! dont listen to them get a simple 675 or 750 holley street avenger or dominator carb around $400+ but it'd give your car that extra kick and would run way better

hello, im new to this so bear with me. I want a set up on my 1971 duster 340 so that it has 2 2barrel side mounted DCOE weber carbs probably 40mm's but the only problem is that from the intake i need an adapter elbow something that will go fit on the 4 barrel intake to 2 2barrel side mounts one...
