I have used both before, no noticeable ill effects from either. I see Prestone mixes distilled water in their 50/50 coolant. Canadian Tire says Deionized water because they sell it. It is going in the big Autocity 2core aluminum rad which cools the 403 easily. Thoughts
I am putting back on the droning exhaust on the 70S. Sounds good outside, inside, not so much. I plan on adding a pair of 12" long resonators. Just before the mufflers or just before the exhaust tips are the only real options for placement. Vibrant supposedly recommends mid way in the vehicle...
I have decided to work within my budget and not go with the 403 build. It will be an iron head, roller cam, Olds 350 with a 4.125" bore and 3.5" stroke and a 2004R and 3.90 posi for my 70S. I already contacted Parkland Engine Builder's for machine shop price. I plan to have it stripped out by...
I plan on building this 800 cfm model that came off a 85 Buick station wagon with a blown up 307 swirl port motor, had it for 23 years to replace the current super lean current 83 carb on the 70S. I plan on totally recalibrating it for a 220ish duration cam. I need to figure out the air bleeds...
As I move closer to building my 424 SBO, the motor itself doesn't bother me as much as the trans and rear. I know the motor will be 400+ HP and 500 ft/lbs. My long term goal to lay down the hammer on all but the highest power modern muscle cars is a beefed up 2004R with billet parts and 3.90...
How it currently looks. 9 to 1 Olds 350 214/214 cam/TH350C/2.78 open type O rear.
I have been fogging the back to cylinders with this.
#7 and #8 were 110 psi vs 150 to 155 for the other 6. I gained 15 psi on 8, maybe 5 on #7. No real gain this 3rd time but will use up the can in those...
Does anybody know the back spacing on these? A local wrecker supposedly has 4, a 2wd rim is rare up here. I am thinking of these for the 70S with an Olds emblem over the bowtie.
Ok so I have the B+M weights, #4 and #5, I believe with stock springs. My 1-2 is about 4750 rpm and 2-3 is 5200+, I let off. I would like both around 5000 rpm, slightly over I can live with. Does one weight affect one shift or the other or both? What about springs? I am finding conflicting...
I mentioned finding SN Valvoline VR1 20W50. It is supposed to be quite high in ZDDP. This time there was this on the shelf so I grabbed a couple of bottles.
Along with the stroker 403 upgrade, I plan on the Sniper returnless EFI module. Of course that means replacing any chunks of hose in the system but not adding a return line. I like the idea of the Qjet flange Sniper with the fuel line positioning and air cleaner positioner for a factory style...
I did a post on Classic Olds but never really found my answer til my last search. My understanding is a ##W40 or a ##W50 weight oil is exempt from the 800 ppm zddp SN maximum which is just weird and doesn't really make sense. It does make me rethink certain oil I assumed were no good because of...
I plan on getting the 424 ci 403 short block together next year. I have ported #6 heads with positive seals, 2"/1.625" valves and filled crossover's. Other than new springs for the roller cam along with new positive seals, I will probably leave them alone. Problem is the 55cc chamber, it puts at...
Anyone who restamp's regular low value parts as valuable W30 parts are horrible people. The guy who has to have every part date coded, pays ridiculous money and looks down their nose at anyone who's car isn't is also a horrible person and has ruined our hobby. Personally, if I bought a W30 and...
For some reason a person built the tiny 12 x 24 foot garage in a hole during a time when cars were huge. I finally got a truck load of junk to the dump that I accumulated. I have some fairly good tools and now have all the tools boxes on the driver's side. It isn't insulated but does have siding...
First off, growing up in South Western Manitoba, we were AWA territory, I remember Rick Martel winning the World Title and the Road Warriors coming in and dominating. Then they disappeared off TV. I also watched Stampede Wrestling but it was also in decline but still had some great talent. I was...
