Re: Poncho Strato-Streak 1955 287ci Pontiac V8 That grew to
Original 1955 Pontiac brochure printed October 1954.
4 barrel was optional late in 1955 bumping Hp to 200-210.
Hp jumped in 1956 with the 316 ci V8.
Same basic engine foundation was used to 1979.
Tall deck design original at 10.230 ".
6-5/8"- 6.625 " center to center length rods in all Pontiac V8's except for ultra rare 1969 Pontiac 303. 7.080" rods used. Just 15 303 engines made.
NASCAR 366 had unique connecting rods too in 1972.
One year only features of the 1955 Strato Streak 287 was the use of Full Floating connecting rod wrist pins. And replaceable valve guide inserts.
Pressed pins and intergrel cast valve guides used in all later engines.
Fully machined combustion chambers since day 1 of the Pontiac V8.

Re: Poncho Strato-Streak 1955 287ci Pontiac V8 That grew to
those old advertizement pictures are great! , but I will point out that I always wondered why Pontiac blocks seem to have less bank to bank rigidity with the open area in the casting over the cam, now I don,t remember many blocks cracking into two banks but it does look far less rigid, and I doubt Im the only one thinking that way, as the newer aftermarket blocks seem to have added some bracing

There are ways to address Grumpy.
I know how. Did it prior.
Aftermarket Ponch is $5,000-10,000 cash.
Don't need it.
Good for 800Hp min if you know your stuff.
Other option is dish out $50,000 cash for a 1969 Ram Air 5.
1973-74 SD455.

Question of the day.
How did Mickey Thompson run 406 mph in his 4 engine streamliner ?
NO AFTERMARKET BLOCKS AND HEADS IN 1959-1960.
Given 8 389 engines from Pontiac.
A check for $10,000.00.

i think it can be done, not everything has to be billet and titanium to go fast brian.. just err on the safe side and be cautious till you get it sorted out,,, no pump gas just c16 while youe breaking it in and tuning the fuel and ignition. dont need some pump gas piss ruining your hard work the first time out.

No Turbo this year.
110 to break the TA Engine in.
Runs great on 100 AV gas at 32 Degrees BTDC.
36 BTDC I use 110.
Other 455's are Pump gas burners.
Allways used High Octane in the TA.
Don't need C16 118-120 motor octane Phil.philly said:

Re: Poncho Strato-Streak 1955 287ci Pontiac V8 That grew to
Factory Rods. Factory Crankshaft.
Made his own pistons.
Can work again in 2015.
By the time you buy an aftermarket block, Aluminum Heads, Rods, Billet Crankshaft, Roller cam,
$25-30k is spent.
Still have to have an induction system. Sheetmetal intake.
Race headers.
EFI Or Carb to match.
Machine Work.
Engine Dyno time.
Spent $50 k easy.
$50 k I dont have.
How about you Phil ? Have $50 k laying around for an engine alone ?

Re: Poncho Strato-Streak 1955 287ci Pontiac V8 That grew to
hell no! and for 50k you would imagine the shit better make 2000000 horsepower! hahaha yea man i understand completely, how much are a good set of pistons for that thing? or are you going to recondition and reuse some stockers?
heres some cool reading on the s/d 455 i found online... dont know how true alot of it is but they are talking directly to guys that designed and built the engines so it has some clout...
http://www.hotrod.com/how-to/engine/pon ... uper-duty/
some head flow data for some of the stock poncho heads and some aftermarkets... granted, every flow bench is gonna measure different and these guys are measuring on a 4.250 bore

I had a NOS SD-455 CRANKSHAFT , NOS SD-455 RODS, & NOS SD455 PISTONS IN ONE 4-BOLT MAIN 455 .
IT WAS 1996-1997.
About 10-15 SD-455 1973 Trans Ams had the 310 HP 041 RAM AIR 4 SPEC CAMSHAFT.
MOST WERE PRESS TEST CARS.
THEY WERE VERY FAST.
BEATING ALL BUT THE L-88 CORVETTES & RACE 426 HEMI OF 1965.

Re: Poncho Strato-Streak 1955 287ci Pontiac V8 That grew to
for some reason everyone I talk too that is young enough that there's no way in hell they were actually driving around in a new muscle car, at that time seems to take it as gospel that every other muscle car ran in the 12s and a few ran low 11 second times back in those days, yeah I,m sure thier dads car ran 11s off the show room floor just like they told the kid it did! yeah! I remember the days when you could buy a killer crate engine 454 for $1800 and when a new 440 six pack road runner . with a 4 speed trans, could be had off the dealers lot for well under $3900.
well the truth is , tires sucked, suspension science was not nearly what it is today and we still had a great deal to learn about engine building and real 500 plus hp cars were RARE and while they did exist there was then and is now a huge percentage of guys driving those cars who were clueless as to the real power level and a large percentage never visited the track and got a time slip!
an example would be my neighbor who restored a 271 hp high performance 4 speed mustang, he added a aftermarket cam, headers, a new intake and carburator and he has some kind of traction bars and he installed a 3.90:1 rear gear,, and then told me he made at least 400 hp.....so I wonder why the car runs low 15 second 1/4 mile times.
could you build a fast car? HELL YES! but it did NOT come off the dealers show room that way!

Once you had a 455 built to race, nothing less will do.
Think I told you about 1 year ago its hard to beat a Pontiac 400.philly said:
