scored a free 350 on craigslist, assuming the block is solid I'm planning on a rebuild with some more power. Daily driving an 86 choo choo el camino ss


Chevy 350 1969-1980
mainbrgs: std
pistons: std
rings: std
rodbrgs: std
FrostPlugs: Brass + $9.10
CloyesDoubleRollerTiming: Cloyes True Roller # 9-1100SP + $22.19
Camshaft: Comp Xtreme #12-246-3 274/286 adv duration .490 .490 lift + $89.61

going to be paired with a street raptor 2200-2500 stall

also have a set of full length headers from an older chevy truck


200r4 trans, 10 bolt 7.5 inch rear with posi, 2.56 gears, most likely a 3.42 or 3.73 upgrade as well


I'm sure everyone here is familiar with northern auto parts rebuild kits, so this comes to right under 440 shipped.

anywhere else I should be spending money/saving money?

thanks ahead of time. first motor rebuild so I'm trying to do it right.

Please post the compression height of the pistons. I can't seem to find it.

couldn't tell ya, the only source I have is

where it lists the other options.

JMO, but I would change a few things. Assuming you have 76cc heads and need a flat top piston I would get the H345NCP piston, Mahles usually have too short of a compression height and those H345NCP pistons work great in a daily driver. I would also go with a less aggressive Elgin cam so it lasts longer and you have better low end, the 1785 or 1065 cam looks like it would work well with your combo, depending on what you want.

appreciate the 2 cents. Just looking to beef up from the current 305. it's a high output, but that still only equals out to <200hp. I'm trying to get closer to 300hp but still reliable and wont totally destroy what gas mileage I still have. It's a street car, never really going to hit the strip in this stage of it's life, so I guess lower-mid range power.

I have no problem getting a new torque converter or re-gearing, but as always I'd like to keep the cost down, so possibly a setup that could run on what I have now, but would still benefit from a higher stall and a step up to the 3.xx in gearing.

I'm not worried about a smooth idle or higher idle either, so maybe that could influence some opinions.

I'm in somewhat the same scenario and I'll tell you what I have for what its worth. I've got an '86 SS Monte with a 3:73 posi rear, 200r4 TCI trans, and a 350 sbc that I figure is making about 300-325hp.
I can only guess the static compression(9:1)sorry. Its got a Comp. HE260 cam(212@.050"w/.447" lift), mildly ported heads(RHS rebuilds from 25yrs ago)
600 Holley, Eddy Performer intake, MSD HEI, Tri-Y headers, 2-1/2" pipes w/Dynomax Turbo muffs.
It will idle at 630 rpm with 15" of vacuum in drive. No lope really(was going for the sleeper 20yrs ago). 1st gear is pretty much a waste as I usually break the tires loose, with a pretty good 2nd gear. The stock trans would just slip when it hit second no matter how the TV was adjusted. The combo beat the Mustangs of the day.
IMHO I'll second the guy who said your cam was too big, especially with the 2.56. Maybe with the stall & 3.73, maybe. You didn't say what heads your working with. You can make 300hp in a 350 with a smaller cam and life a lot easier IMO.
FWIW

not 100% sure on how I'm going to attack the heads, I'm going to have a machinist check out the block here soon and I guess give me his thoughts. Apparently the guy has built motors for larry mcbride, top fuel motorcycle racer aka "spiderman"

I'm hoping he'll be able to give me some insight.

Imo if you need any block work done I'd skip it and get a good vortec or LT1 core. When you add up all the costs they usually come in for less and make a little more power. Its pretty easy to find those engines only needing to be cleaned and maybe honed- it saves you a lot on machine work.

as soon as I can get the intake manifold bolts undone we should be able to find out, the 4 inner bolts dont feel like coming loose and I can never seem to find my pb blaster when I need it. So I'll be off to the store
