727 torqueflight question

[MrJLR]

I can ship it to you free through my work...you'd only have to ship it back...probably 10 or 12 dollars?

Thanks! Still evaluating the purchase.

Do you guys think a new 1 ton harbor freight lift would safely install the 440 with the trans attached? I know the 440!is about 670 lbs alone. 727?

Yes. I have loaded 727s myself in and out of pickup trucks I think they're approximately 150lbs give or take...

So I decided to pass on that rusty combo and get this ‘76 440 instead. Clean and garage kept, missing some accessories though. $500. I’ll be reaching out for some tips on pistons and 915 heads to improve compression. I’ll watch for another tranny as I progress. Thanks for all the input!

Sonic check the block, decide what the real use/application is going to be. 915 heads are good with a pocket port, 2.14/1.81 valves work well. Pocket porting the stock heads yields real power/torque. 915 or 906 heads work the same, just need to figure the CR you want. Pick the cam wisely, combination is the key.

Core shift is rare on later year blocks. But better safe than sorry. Cherry picker works fine if you just raise the front of the car and lower it over the engine/trans attached to K-frame. Factory style. That also allows you to install almost all of the external accessories before installing. Weight doesn't matter if you aren't raising the engine.

good points 66
most likely could just need a hone but do not bore any more than necessary
want more cu in stroke it
915 heads I have several sets but you are in florida
915 by itself will not give you any quench
guides, seats, valves vs new heads
I D Dished the 6 pack pistons to get the CR I wanted with the closed chamber heads
check right now to see if you have weight on the dampner- if you do you have the heavy 6 pack rods
do not use them use LY rods with Mopar Perf SPS rod bolts and LIGHT pistons- makes a big difference

1.81 valves with hrd ex seat BVVC
or use those heads which have induction hardened seats , keep the stock 1.74 ex and the KB quench dome pistons
see if stock timing chain- see the nylon in the pan
measure compression height at all four corners B 4 Pulling pistons
you have the best carb for the street but you can go lighter on the manifold

for a street car check the torque difference with the cam change at 2500 and 3000 vs the big gain at higher rpms
as IQ says a dual plane would make a big difference
be real sure that you get what you want for your build

I want stock plus a few upgrades to run well on pump gas. Cam that allows stock valve train, headers, alum intake. Nothing radical. Dependability is key. I’m a Power Tour junkie!

Get the correct year output shaft. The spline angle (not spine count) changes 3 times thru the years. Any year tail housing. Trans must be disassembled for the swap.
Doug

Did not know that the spline angle changes year to year or model to model. I've had several dozen 727's & they all appeared the same & mixed & matched numerous yokes. Ya learn something new everyday.

dvw, many thanks. I guess I've always been dealing with the standard non-lockup versions. I completely forgot about the the pre-66 versions. My '65 727 had been converted.
