to stroke or not to stroke, finishing off combo

[Challenger340]

Gotta LUV them street Dom's, they were a sweet Intake all-round !

[SeattleCharger]

I put an ad in the site swapmeet here for a eddlebrock CH4B dual plane intake, took a little while, but then I got two different responses from people selling them,

[dukeboy_318]

hey ron, i know you seem to swear by the proform carbs, how easy or they to tune and run compared to a holley, power vs cost benefits, in other words is it worth the stack of bills to get?

Chris, the Proform carbs are basicly the same as a Holley "Ultra HP" model but for several hundred dollars cheaper. They tune exactly like a Holley carb and in most cases the fuel curve is dead on. Depending on the combo it might need a jet swap but that's it. All of the high dollar features of an HP series carb w/o the high dollar price tag. They are most definately worth it...and more !   

On a stroker build this is a no brainer

[dukeboy_318]

what size, i was thinking 850, think thats enough

[firefighter3931]

With a low rise single plane like the Street Dominator the 850 Proform would be perfect on a 470, inmo.

okay, now that the rest of the combo internally is set, just need to come up with the fuel pump and timing set, thinking a carter 120 ph 8 psi mechanical pump, 3/8 lines. not sure on timing chain and gears, but i know i want the double chain, possibly from crane or comp any opinions

[mally69]

Firefighter, how does the TM-7 compare to the teamG and the torker. Im just kinda curiose cause thats what on my current 440.

The TM7 is an excellent manifold....on par with the Street Dominator. On my engine it was allmost identical in terms of hp and torque.  It's more of a hot street/strip manifold....3500 stall/4.10 gears

The Torker also makes really good power but it starts to fall off at 5500-5600 rpm so it's not the best choice for a strip build but it makes really strong power down low. The runners are tall and narrow but the volume is "smallish" making it responsive at lower engine speeds....2500 stall/3.23-3.55 gears

The Team G doesn't work well with any combo....i would rather visit the dentist than use it.

wow you really dont like that team g manifold

Chris, the Comp Cams chain/gears works great....use it and don't worry. 

I've had good luck with the carter high volume street pumps rated at 6psi/120 gph. There have been some reported failures as of late with Carter products so be aware that there could be a potential issue. Not sure what is going on or if a bad batch made it out the door ? 



Ron

[dukeboy_318]

YEAH!!!!!!!!!!!!!!!!!!!!!! I got my intake in finally today, holley street dominator for 100 bucks shipped  cant wait to get the rest of my parts i need.  ron, will a high volume oil pump suffice in this stroker seeing how it will be driven on the street as much if not more than on the strip???

[firefighter3931]

Chris, Nice score on the SD intake ! 

On mostly street motors i prefer to use a HV pump with a hardened oil pump drive. I like the bearing clearances at .0025 on both the mains and rods to allow for thermal expansion. Street builds run longer and build more heat than a track-only motor...maintaining good oil pressure at low engine speeds is priority #1 inmo.

okay, im trying to get this all in one place, so is the map of my engine build up minus push rods and bigger valves for the 346 heads, trying to decide on those yet

77 400 bored out .030
440source.com 470 stroker kit, internally balanced, flat top pistons for a CR of 11:1
holley street dominator intake with an 850 carb, possibly proform or holley
Comp cams timing chain CCA 2104
Flowtech headers - 1.75 inch primaries to 2.5 in collector- 78070
carter 120 gph mech. fuel pump
LUN-60305LK cam, .533/.552 valve lift, 242/252 duration with lifters or would this cam be better for my car being that it'll see the street more than the strip( http://store.summitracing.com/partdetail.asp?part=LUN%2D60304LK&autoview=sku )
LUN-77012 valve locks
LUN-75702LUN valve retainers
http://store.summitracing.com/partdetail.asp?part=LUN-73815 valve springs
3500 RPM stall converter
4.10s rear gears
will be running the stock head for now while i save up the extra cash for the 440source heads, but i will be putting in new valves and maybe porting them myself
any suggestions or changes are welcome

[dukeboy_318]

Ron, just wonderin, do i need to make sure i get pistons in this kit that feature valve reliefs, or will i be okay with regualr pistons.

[firefighter3931]

Ron, just wonderin, do i need to make sure i get pistons in this kit that feature valve reliefs, or will i be okay with regualr pistons.

Chris, all the 440 source 470 stroker kits have some valve relief area in the pistons for increased valve lift. 

The slugs you want for yours will have a 4cc valve relief which will yield ~ 10.5:1 compression ratio which is perfect for a pump gas street build with closed chamber aluminum heads.

SWEET!!!! Now ive gotta get the money to order the lit, hehe

[dukeboy_318]

anybody reccomend any particular torque converter, 3800-4500 stall is what i need

[Hot_Rodder]

How about PTC? http://www.ptcrace.com/. These are who I'm planning on going with when I go to get a converter for my 505.  The best way to get in touch with them is to call them, in case you decide to go with them. I've had one of there converters in the past, no complaints.

[firefighter3931]

  PTC 9.5in converter is what i would use.....$450.00 at CRT (Cope Racing Transmissions)

hey, ron, quick question, would you use a stock style kickdown linkage or an aftermarket cable system on this combo?
