82 HO motor with a performer 302 and a 4160

putting on cleaned up E7s with no thermactor humps

shorty headers

2.5" h pipe

2.25" ultraflow catback

ballpark on power gain? I said around 30rwhp. So I'd hope around 210-220 at the tire....I'm more interested in the torque gain from some actual compression. I figured compression would hit around 9.4:1....

82's have roller cam? you should just dump in a running mark7 motor, i thin it will take you less time than swapping the heads, possibly cheaper. i got a great mark7 motor for $400 dropped off for my sister's car.
then put those mods on it.

by mark7 i mean 87+HO, cheapest and less beat up in the mark7's and plentiful in the junkyards.

[evlgt85]

82's have roller cam?

No. But HO does not instantly mean roller cam, either.

[gtluke]

okay
i wouldn't bother with anything till i put an 87+ motor in it if you want to keep it stockish.

[Hooptie]

How about this.

I have the heads. I have roller tipped rockers and I can get the headers for nothing.

Total investment? catback, cheap h pipe and....my labor.

edit: and a gasket set.

[gtluke]

i don't know anything about the roller setup, does it just convert?
if so, do that.

[Hooptie]

they're roller tipped, not a full conversion.

Lifters are still old gay flat crappets.

The motor isn't forever....it'll eventually get saved in a sack and a newer motor....maybe even a mod motor will go in.

[jonmark1985]

are you going to roller cam or keeping it flat tappet?

roller cams are about $150, plus the spider (junkyard special $10?), plus roller lifters ($5-8 each),

personally with the edelbrock intake go to your local parts store and get a flat cam melling cam number mtf-1 some ht900 lifters from sealed power, that cam is the exact same specs as an edelbrock performer cam for a 302, also you may want/need sealed power vs896r valve springs wich run around $5 each, and they can handle .560" and shouldn't need much modification to use them, you may have to use a retainer number vsr7017r also.

thats if you want to go to all the work of changing the cam, i wasn't sure if you wanted to or not, but i figured i would throw that two cents in

personally i would and i think with the E7's (mildly ported), cam change, headders and better four barrel your talking about a 50-60 flywheel horse gain

[Hooptie]

I'm only going heads deep. This is a cheapy weekend project on the DD.

[jonmark1985]

did you do any port work to those heads? im in the middle of doing up a set of e7's they're getting

1.94/1.60 valves
port matched to fel pro #1262 on the intake side
ported exhaust side
removed and filled thermactor bumps
polished chambers
springs that can handle .560 lift
milled down .030
stud mounted 351 cleveland rocker arms
bronze valve guides

[Hooptie]

I'm just going to clean up the chambers and kill the thermactor humps.....maybe a little clean up in teh intake and exhaust, but nothing major at all.

I'd love the car to break 200 at the tires, and the heads, roller tip rockers, headers and exhaust, I think thats 200% doable. I'd think it would be pushing 300+ft-lbs too.

Hell, my 8.5:1 flat tappet 85 motor made 185hp and 285ft-lbs through an AOD with the same intake/carb and a 2.5" h pipe and superturbo catback....

[jonmark1985]

make sure you get the pockets going into the port, that really is the first thing that needs done

Hooptie since this is almost the exact setup I had planned on doing, I think you will come real close to your hp goals. As for the torque, well you'll find out. The only thing that might give you problems is push rod lenght....

[Hooptie]

really? I won't be milling the heads at all. Just dropping them on.

[SchoolBoy]

If you do anything to them, remove the smog bumps.

[Hooptie]

Oh, thats the thermactor humps, and they'll get some lovin'

[1kwik85]

Sounds like your on the right track. You will definately notice a difference. Just the bump in compression will make a huge difference in the way it feels.

[Hooptie]

Brought them out of the car....time to attack with dremel.

edit: I forgot, a good write up on killing the thermactor hump?

[jonmark1985]

i would also match the intake side to a fel pro #1250, im doing the #1262, but man is that alot of work, i don't want to turn the start of the head into a funnel so im having to almost a complete port through then entire runner, the e7's almost already match the #1250, also after you grind the thermactor bumps out i would get a high carbon rod and put a tack over the thermactor holes when your done then grind them smooth again, the gain may minimal, but at least you can say you did that too and i don't see it taking much more work

[82HATCH]

Sounds like you should hit your goal. Let us know how it turns out.

[Hooptie]

I still need to get a how-to on killing the thermactor humps.

They're right there, but I need to know how far to go...etc.

I've lightly smoothed/cleaned up a few intake ports and the exhaust openings, but haven't gone too far in yet...need new bits.

[jonmark1985]

just smooth take them out and make the port look like they were never there, ill get a pic of a pre smog 289 to use for example later tonight

[Hooptie]

good deal!

I just want a reference.

[1kwik85]

Might check out carbdford.com they have a tech article that shows how to port E-7 heads. Just look at the pics and you will get a good idea what to do.

[Hooptie]

Thats exactly what I wanted!

More for the humps than anything.....All I'll do is clean up the walls, kill the humps and polish the chambers.

Nothing overboard since its my first job at it.

Then just throw them on.
