stall speeds/difference

Postby generaljake01 [OP] » April 2nd 2009, 1:23am

I have put in a v-8 and hooked up to the 700R4 from the van and since the trans and torque conv. were new (less than 2000mi's) i left em in and am now questioning whether or not the torque conv. will work properly/have a lower stall speed. Seem like i read somewhere the 4.3 stall was 200-300rpm lower than the V-8...any input???

Sure a looser T/C would get you into the power band sooner,but at a cost of increased heat.Just make sure you cut in a tranny cooler and you should be fine with what you have.You'll find many,many members here with V8 swaps that have done just as you have. :thumbup:

yeah that 305 wont be in there long...Ive read that those(mine) 305's have about the worst flowing heads, the doggiest freakin intakes, and if memory serves me i think the compression ratio was around 2.75 to1 :rofl:. I think the only good thing on the whole block is the roller cam...oh well...IT WAS FREE!! it only cost me the fuel it took to get it home from a town 21 miles away...cant beat that. THANKS GRANNY!! :driving: Trying to talk wifey into lettin me get a stroker :animals-deadhorse: she doesnt understand why i need a bigger engine... :layrubber:

Don't word it like that to the wife. Say this instead, "I want a more efficient engine."

Thats a good idea 355...Ill have to try to come up with something cause every time i mention or look at a new 383ci she just comments..."what is wrong with the engine you just put in...or why do you need that much power anyway??" I guess most women just dont get it... The question SHOULD be why not a engine with 400hp and 435lbs torque?? :layrubber:

Well you might want to find a friend who owes a 383 that will let her drive it on highway speeds.Then she might not let you alone until you get one. :layrubber: :rockon:

Thats the funny thing...shes sortof against buying a new engine but when i had the S-10 on the road she insisted on using it for her work rig cause she loved to drive it...and in her own words..."I LOVE the way it sounds when i pass someone" and she always liked the fact that when you wanted to pass someone you could "git-r-done"... I think theres hope for her yet... :greetings-cya:

I guarantee you that any V8 putting those numbers down is a very efficient engine. :mrgreen:
