Advance cam 4 degrees. Give it as much initial ignition timing as it will take and as quick an ignition advance curve as it will handle.

on my 78 MH 440 in my 88 truck I just installed the 440/727/3.91sg in it. ran strong but... then the edelbrock RPM intake swap woke it up.

I am going with the whiplash 440 cam from hughes with their drop on matching springs. (spring swap heads on engine)

I have a holley street dominator intake to use with a edelbrock #1905 q-jet(thermobog replacment) and will be adding headers over the center dump manifolds/glasspacks.

on my smogger 78,000 mile MH 440, the RPM intake alone on the 440 was a huge improvement on torque and throttle responce. with the 600cfm edelbrock and the edelbrock q-jet with adaptor.

if the whiplash 440 cam does what the whiplash roller cam did for my JY 318 in my 85 truck... look out! and it will

FYI, if you 440 has a cast crank/bullet nose damper-the 440 can use the 400 weighted TC. 383/400 440 cast crank all use the external balance.

if the 440 has a thin damper it is internal balance so keep that in mind use stuff from the 400.

I have 2 sb roller whiplash cams 1 440 whiplash cam going in. and 2 other mopar buddys just went to the whiplash cams in their trucks... we were all running lunati voodoo cams.. but we fixed it now going whiplash.

I like the Whiplash. I want to save my money for my build, but you have me thinking. This 440 could be in there for a while.

Here is a pick of the 400 I just popped.

mines been in since 2010 now and a weekend-some what a daily driver when the 85 is down.. the stock cam is not all that bad from a MH..plenty of lowend torque with the RPM intake but it is all done at 5000 rpm about 4600 rpm with stock points bouncing. but some NOS Accell 32oz spring points fix that and now pulls to 5500 and out of steam.

about 1800-2000 rpm would get me 15 mpg with a q-jet/3.23 gears, 3.91 drop it back to a flat 10 mpg.

I would have no problem dropping in a bone stock lopo MH 440 with nothing but a RPM intake and good carb..headers if I had them.( I run 2 center dump truck manifolds now till cam swap with headers)

the 440 truck does well with 3.23 gears on the hwy and city driving but the 3.91sg is a blast to play with.

scratchin...what kind of (in town) MPG do you get out of that smogger 440? just curious...

Not to hijack this post, but how do you like those headders, and are there any issues with spark plug fitment, and or boot contact/melting

Wonder how they would fit in a 4x4 with the center dumps, and front axle location.

Don't want to highjack thread but since you have run the whiplash cam in a sb how was it for street drivability and mileage ? converter ? thinking of getting a small whiplash or thumper for my 360 in my 77 shorty van and adding airgap and headers. Don't care about how it sounds just want something that works with the low comp.
Thanks

thumper take comp/stall/gears to run on the street with out being a dog under 3500rpm. IMHO.

the whiplash works great with my low stall TC and the 2.76-3.21-3.55 gears I have ran so far with the auto trans. very good street driver and drives like a stock engine until you mash down on it.

the NV4500 5 speed behind it now and with 3.55 it smokes 1,2,3rd gear and then wants to wheel hop in the truck.

I have a JY/used 107,000 mile 91-318/#302 heads/eddy 600/LD4B/headers/2.5 duels gets around 18+ mpg with the auto or 5 speed maybe a little better with 5 speed if you don't mash on it thru the gears.

winds right up to 6000 rpms in my 318 and I am running the comp 901-16 springs with the roller lifter/whiplash roller cam. so far no issues.

I have plans for 2 more SB318s with the roller whiplash, 1-318 with 360 heads 2-318 with magnum heads.

Hughes was not to sure about the roller whiplash in the pre-mag as they have not run that combo.(worry of cranking PSI/cyl pressure) when I asked about the springs.

comps are little less on the seat and higher rate over all/hughes is more seat-less over all.

the whiplash is almost same specs as the lunati voodoo roller cam I was running with the comp 901-16 spring as well.

but the whiplash woke it up a lot more than the smooth idle voodoo cam.

does just what they say it will do for a stock smogger daily driver.

I rolled the dice with the magnum roller whiplash and comp springs...so far the comp springs are doing a fine job...no valve float or valves bounce on the seat.. revs till it skears me enuff to lift.

I very happy with it in my junk and the 440 should be even better.
