ideal camshaft
hi everyone!
my truck died last week, it was a sad day, i burnt out my tranny and found my motor is blowing through oil 3-5 quarts a week, its coming out the pipes and the engine compartment. so none the less i need to replace it. i am going to use a 400. i am using arp bolts all around, badger flat top pistons .030 over. its also going to be 4 bbl, with a edelbrock 600 cfm, because thats whats on it now. the motor is primarily going to be a low-mid range powerhouse. i got a new tourque converter that gives me a 1650 rpm power start range. what would be the ideal camshaft? i am going to plow snow whith it, rarely pull a trailer, do alot of highway, and i want it to get loads of power. whats a good cam to use? thanks for any help!

You might want to rethink the converter. A high stall converter is usually only used in racing applications and adds a LOT of heat to the tranny besides guzzling fuel. Let your gears do the work for snow plowing. On the highway that converter will eat you alive. Use a towing converter (low stall) instead.

i know this is an old thread but i want to bump it a little and ask how that is a high stall converter. to me thats about stock isnt it, my trans was rebuilt b4 i owned the truck and a 2000 rpm stall was installed along with a stage 2 shift kit, alot of fun to drive and i get about 12 -13 mpg with an edle. intake 600cfm carb and ported and polished heads. how much would i gain in milage if i went to a lower rpm stall converter and whats the best stall, i to do a rebuild with either a 255 deh or a 265 deh cam so what would be the best converter. neways thanks for the info

At the time I looked up some specs on a website I found that had some decent info that made sense. I lost the link so I can't send you there, Good old Google search time. AFAIK the stall speed depends on the engine build and the converter. There is a lot of conflicting info out there. Good luck!

what is the stock rpm stall converter. also i plan to make a daily driver and want to make sure that im right in what im thinking the 255 is going to be more low end torque and better fuel economy (given that i keep my foot out of it) while the 265 is more mid to upper hp less economy right?

I spent 6 years Plowing snow. You'll find that the Ideal plow truck gets around town like a Ferrari but they suck to drive the highway with. I would suggest a stock converter but a well shift kitted transmission. (built for tow big time) You want the shifts to hold off late and be very firm when they do come. You should be in four low when your plowing anyway or you'll be stalling the convertor and burn up the tranny. As far as camshafts go I think the 255 would be better because it puts the power at the bottom of the curve and it will idle rock steady. (so i've heard) the 265 idle is rough enough that it would be annoying in the plow truck all night long. ( approaching the curb or the stack) You will probably rev it higher in reverse than anytime going forward.
Oh well ...good luck on this

Comp Cams XE256H Xtreme energy cam sounds good. It looks like it has a lot more aggressive ramps, even more aggressive than the Magnum HR cams. Comp cams has done a lot of valvetrain dynamics research lately. Make sure you get their complete kit with springs etc.
