Not looking to hijack the thread..
But I remember an old Hot Rod Magazine that had a big article on the 215 V8. They had a graph that showed what bore, stroke and heads to use to bring the 215 up to a 350.
I'm pretty sure they even used aluminum heads.. I have nothing against a SBC.. But I'd be curious about the weight difference of an Aluminum 350..
I have to try to find that magazine..

The alum 215 weight is about 50lbs less than an iron Triumph Spitfire 4 banger. In MI, theres a guy that did this to a spit!!!!! Sunbeam Tigers never had a chance, no hood scoops, no signs that it was other than stock.......... till he powered up. Bob

what - no new pics : (

per these charts - the sbc is almost twice the weight of a buick 215 - 575 vs 318 - and the porsche 914-4 is 265 lbs - so a 300 lb increase - that's it - no more passengers : ) except for carmen electra : )

so a sbc doubles the engine weight over a stock 914-4 but adds @ 200 more hp - and increase the overall 914 weight by 10% or so - seems a reasonable compromise.

the nice thing about Porsche color Tangerene is that it can be swapped for Chevy hugger orange and its priced like a chevy color

if teh heads were not rebuilt I strongly recommend changing the valve guide seals now while its out and easy to do. they are VERY cheap and head removal it not required

Jim, 575 would be with stock intake, all accessories and stock exhaust manifolds.

Your aluminum intake removes probably 40lbs and your headers probably 10lbs. If you had aluminum heads it would be another 50+!

Jim, I forget and I'm too lazy to look back. Are you adding any stiffening components to the tub while you're doing phase 1?

I've got 1/3 of the Engman welded into mine but....my phases are kind of running together (and taking really long, I might add).

This is great for you getting so much knocked out in one shot. Can't wait to read you're back on the road!

Aluminum heads....50 lbs savings...hmmm.

Wonder if you could do a head swap without removing the engine.. . .

You could lower the engine down at the front and do it, but then your dead lifting 60lbs of cylinder head... each head..

Instead spending the 2 hours to remove the engine/trani would be the way to go..

gear stack pic

my plan is to ...

delete 1st gear - block it off.

2nd = stock F

3rd = flipped V ( equal to using an R )

4th = ZD ( move ZD from 5th to 4th position )

5th = H flipped ( as overdrive )

Jim,

What kind of RPM do you expect to see @ 60-70mph cruising in 5th with that flipped H?

Of course that also depends on tire size, which you're relatively close to stock IIRC?

according to this chart - using 205x50x15 tires - and HA gets

62 mph at 2500 rpm - vs - 55 mph for stock ZD

and

74 mph at 3000 rpm - vs - 66 mph for stock ZD

my tires are 195x60x15 - slightly taller - so speeds will be slightly higher if i was using a flipped HA and higher again due to i will be using an H

Jim,
I just run an H and the gears feel just right, with 16" rims with low profile tires. Will you have a higher ratio for 3rd and 4th than stock? It seems like your going have about the same hp and torque and as I do.
Mark

PS I was going to do something similar with the gears but evil talked me out of it.

with stock gears - i feel that 2nd 3rd 4th just wind out too fast - so the plan was to replace 3rd and 4th with one gear ratio centered between 2nd and 5th - and then add H as more of an overdrive for highway use.

since this set up does not require buying any extra gears - i figured it is worth a try in my 225hp +- car.

Throw some 285 35 18's on there (aka 25.9" tall), that'll help wind it upslower (IMG:style_emoticons/default/wink.gif)

I just did a couple of runs today and it really felt good. 3d gear was very nice and I had some good good power from 40-85mph.


And also why get rid of first? I use it all the time when for some reason im having a hard time getting it into 2nd..
