father son 1/8 mile battle

[DoubleV]

He had real low compression on two cylinders. Dont remember how low off the top of my head. He has the motor apart now and is trying to make it faster than my 350. He's doing a new cam. 1970 stage one heads, and new pistons about 9.6:1 compression. I still think I'll have him. Someone told me to try a 650 double pumper to try to make a better time. They think I'm leaning out in the top end

IF your dad rebuilds the engine properly, it's tuned correctly, and he has traction, he will SMOKE you! Should be in the 12's easy.

I see this post is still going - If you look back you will see my 455 ran 12.7. 79 as mentioned - for want you have in that engine it's weak, your only putting down 250HP.

Which engine has 250hp? I know my 355 has a lot more than that. My 305 was around 250..

Your engine! Run your numbers and that's all the HP(250) your putting down. A 350 .040 over is 357 cid

The fathers engine isn't that big of a shocker. The 76 Buick 455's were pretty pathetic. Throw in some wear and tear, and low compression, and voila! you have a one hundred sumthin HP big block. Its about all the open chambers could muster up.


If he manages to get the early heads, 9.6:1 compression, with stage1 valves in there, watch out. Buicks win races in the beginning of the race, so if he doesn't have a lot of traction, or the suspension is out, it'll hurt the results.



Some stuff to sort out in both engines, but sounds like you guys are having fun.

Do you have any proof that it was 250hp or that your current engine has more? Not just seat of the pants proof im talking actual numbers. I highly doubt that 305 from your old thread had anywhere near that. Most crate 350s come with only 290ish new.

But with vortec heads, a bigger cam, 10:1 compression and a 600cfm carb seems more than 250hp.. if it is that means im getting less than 200 at the wheels after going through my 700r4..

I think he means you have 250 RWHP.

Keep in mind it's not how awesome your engine looks like on paper. It's about how well it was put together and how everything works together. Your engine specs say 'look at me, I'm a high performance engine' but all those cool numbers may not be working very well as a unit hence your mediocre performance. My practically stock Olds 350 at a whopping 8.1:1 CR, dinky-*ss Voodoo cam, and stock iron heads went 13.83 @ 96.85 in my car. So only a hair slower than you and look at my pathetic build! Why are we running so close yet on paper your engine should crush mine? Could just be in the tuning, your selected engine parts don't work well together, or something isn't what you think it is like your 10:1 CR is really much lower and don't work well with your cam. My 350 may have been extremely mild, but everything worked well together and it was in a good state of tune so it ran better than what most would assume.

P.S. A bigger carb would be better for you.

lol, my old mitsushitty galant would of beat your dads time... was a 99 mitsubishi galant with the beatnick 3.0 v6... ran mid 16's stock... after a buddy put a chip, short ram, headers n exhaust, lighter rims, it was down to high 15's... then i bought it and tore it to pieces, the removal of EVERYTHING i could unbolt, ie back seats, trim (both interior n exterior), door panels, console, carpet, spare tire, etc it got to mid 15's... all that said, if your dad builds his engine right, he should be able to leave you in the rear view mirror, but you have the posi on your side that will help ALOT... keep us posted, would love to hear how thing turn out after your pops rebuilds...

That's the big thing, I think. Having fun finding where you are now, and having fun finding the right tweaks/changes to make them faster.
