Rice is for dinner!

I have two B-bodies: one is an '85 Impala 4 Dr Sdn 9C1 powered by a BBC, the other is a '89 Caprice 9C1 powered by a 406 SBC.

Both are "built" with the BB running low 9's on slicks, the SBC running mid 11's with 235R15 Goodyear Eagle black wall cop tires.

Both look like old taxis with flat hoods, and aside from my rumppatta rump cam and stainless steel Bowtie exhaust tips pass for stone stock. I drive both on the street, tagged and insured, though the BBC has traction issues with street tires, so it isn't as much fun as it used to be when it was only a ZZ502. Anybody else consider this normal?

Dave, I'd love to see pictures. When I get around to upgrading my Chevelle to a fuel injected 502, my '82 Caprice will hopefully become the new home for the 454 that's under there now. Any issues installing a big block in there? Did you bother keeping the A/C intact? What modifications were needed?

Wink How not to be seen

The B-Bodies I have ran from 1977 to 1990 and share chassis parts with the '91 through '96 year cars. The BBC motor drops in with Chevelle headers, and Camaro headers on the SBC, though once again Chevelle headers will fit (I chose them to keep it smog legal as there was talk of inspections for large metropolitan areas, and the Camaro headers had air pump fittings).

I had to reinforce the frame on the upper drivers side as it was pulling the chassis side stock four link mounting point out of the body. I replaced the 8.5" 10 bolt, with a 1971 12 bolt out of a Chevelle running a 4.56 Richmond gear with Eaton posi and still spin the slicks.

Went through three built HD 700R4 trany's before settling on a 4L80 E. I would recommend going with a TH400 and a gear vendor as it costs about the same but there are more HD parts and goodies for the TH400.

As a ZZ502 it ran on the street for three years, with A/C off a '72 Chevelle. Though I had to use a Griffin aluminum radiator and a HD trans cooler for the 3400 street fighter lock-up torque converter. Great fun, stomped every body, and every thing around except the fastest Camaros and Firebirds, and they always ask for a rerun at the next light as I took them on the "top end" first time around.

Tore the "six quart" truck pan off the engine cruising down the interstate one night, so while I had the 502 apart I replaced the pan. Then the cam and lifters, then the heads, then the intake, carb and finally stuffed a 4.375' crank after boring the block out to a paper thin 4.60" which required hard-block along with new pistons and rods. I kept the 502 decals though.

Red face Finally a picture or five

The beige '85 with the primer hood is the BBC powered car note Autometer gauges on dash as only visual clue something out of the ordinary.


The '89 9C1 in the fore ground was my wife's old squad car I bought at auction it was recently converted from a 305 HO to a SBC 406.

Here is an old picture of the BBC back when it was only a 502


I started to rebuild the 502 so here it sits after new pan and cam swap. But then I got a hold of a another BBC a 555 so I started to merge the two.



I severed my Achilles tendon which delayed me getting any work done for a year or two so here is the 582 today.



I needed to replace the 305 in the '89 as it was getting tired so the SBC 406 has had priority, but now I'lI have time to get the bugs out of the big block (such as melting the transmission control wiring).

Thank You!

It has turned a few heads. People can hear me sitting at a light, but even sitting at the light for a minute or so many are still looking around searching for an obvious thumper they just can not see. I will sometimes blip the throttle or purge the NOS to get their attention (just for shock value). The expressions I get when it dawns on them is priceless (well worth the price of the giggle gas anyway).

That's badarse! My grandfather has a beige 82 Caprice classic that came from Florida. It's absolutely pristine. I'd love to drop a big block in that. Hehe!

NICE sleepers, and to answer your first question; I don't see anything 'ab-normal' in any of it.

If you don't know exactly what you are looking at, my '96 appears to be bone-stock SS with 'Grandpa' driving... the bad news is that it comes out of third at 135 - headed to overdrive... (I don't play 1/4 mile games). I run out of speedo (and testosterone) at 160 - the tires are good for one hour at 168, but I will lift slightly before that. The new motor and tranny (waiting on cooler weather) will make 'some improvement'...

One of the 'really old guys' in the local club has a Roadmaster wagon (with the skyliner glass in the roof). $1800 for the car, $8k for the 396 stroker, backed up with a 6 speed, 3" exhaust, stock Buick rims (rears widened to suit a 285 raised white letter tire - that he had a white-wall shaved into for a consistant 'look'!). Oh, did I mention that he's retired... he was a GM racing engineer.

Good to see some 'crazies' on this forum!
