questions... low oil pressure... MPH gain in the 1/4 from head's ETC
OK, well ive been saving every dime i make for the last six month's trying to get a house. We are very close to getting a contract for a nice place, just waiting for the bank that currently own's it to approve.
Anywho. couple thing's been running around in my head, and wanted to pass it by you dudes.
1.) Oil pressure in my car is fine at start up, and for a good 10-15min driving. But after that oil pressure drops (STOCK GAUGE) to one notch above low/red/danger/w/e.
I know the stock gauge is worth nothing, but it use to never have a issue really. Only real thing i changed was i run Mobil 1 synthetic oil now....
2.) At the track last wedsday i was BS'ing with a guy who just put a trickflow top end on his hatch 5.0. we where shooting the sh*t and found out he has some dumb stuff like stock throttle body and missing a few odd's and end's that would net him some good power.
Biggest one is that he was running 10* base timing "so it could pass emmissions" I gave him **** for it for the fact that he could run alot faster, and it takes 5min to change.
We bumped it from 10 to 15* base, and he picked up 4-5mph, and droped a hole second from his ET (mainly from me telling him not to dump the clutch on street tires) up in the 1/4...... Now i have more bolt on's then him, and micky thompson's, he's on street tire's but has heads and less bolt ons'.
Is it possible for me to pick up 7-8mph in the 1/4 just from head's considering thats the only real thing missing from my combo? (other then a bump stick.) (I trap 7mph lower then him)
3.) Would porting the upper or lower intake of my typhoon intake help anything? I'm guessing NO with stock head's, but if i had say twisted wedge head's, would porting the typhoon help anything?
just wondering sence soon enough ill be able to spend money again. and id like to run some decent time's without the bottle.
hopefully the low oil pressure and puff of smoke i get here and there when WOT is not the engine dying on me.

If I would I I would get a newer motor and put it on a stand to have ready (not saying yours is). If you havn't port match your intake to your heads I would. So what were your times?????????

Well i dont want to go with 302's anymore. i want a 351!
I plan on slowly building up a 351.
408ci, all forged
AFR205cc heads
dunno on the intake yet. something street friendly.
I was thinking 5.0HO cam to begin with just to keep it secret on the street, and see what kinda power it make's.
150-200shot of go-go juice.
should run mid 13's on motor (at 8300ft DA) I hope.
I only got one run on wedsday, no bottle, girlfriend in the car. Ran the same thing's before the shocks, struts and control arm's, but i did almost NO burnout and it hooked like hell. it was sweet!
on the next pass with the rear shock's stiffened up, and bottle ready to go it started raining when i was 5-6 car's back, and they closed the track.
This Wednesday i have a training class at work, and MIGHT make it to the track, but weather is saying good chance of rain............

That would be nice, but i like the idea of running a stock cam for now. I honestly just dont want to put more money in this motor. Maybe ill buy the head's for the 351 first and bolt them on this motor and see what it does......... lol

cool, that's what i like to hear. if i was running the time's he did i would be happy..... for now. I just hate having to use the bottle to run decent time's.
compression test's today where good. kinda LOW PSI due to the elevation im guessing, but every cylinder was very very close to one another, only one, the #7 cylinder i think, was about 10psi lower then the rest. (my notes are in the car, im guessing of the top of my head, but i know it wasent anything serious.)
hopefully this thing hold's out. I originally budgeted $5k for the 351 and supporting stuff. but look's like ill be around $10k, and it might go over that :/

his lack of traction out of the hole will result in higher trap speeds at the end of the track. so don't be too worried about that.
As far as your 408w plans go... bigger heads should be used, I'm running 192cc heads that are slightly ported to about 200cc's and they are a pretty good match to my engine.
so if my 347 runs ~200 cc heads, dontcha thing a 225 may be in order for your 408w?

true, didn't think of that. the street tire's might give him 1-2mph
IDK, i was thinking along the line's that at this elevation (5880ft at the track, DA is 8200-8400 in the summer nights) That the 205's would be better?
the 205cc was more of to make good power, but be low down torque monster too.

Aha I was gonna say 13's on a 408 would be a joke, till I saw that. You should be fine with the 205's, I just run victor jr's on my 408, they're 210cc, and she runs like a champ @ about 1500ft. Just threw some shims underneath the springs to bring the seat pressure up about 10lbs, and bolted them on.
Are you going to go EFI with the 408, or Carbed? If you're goin' EFI look into the Trickflow R intakes, have nice long runners to keep it nice and torquey in the bottom for the street.
Also, don't leave that 5.0 cam in there... you will never, ever be happy. Spend the 300 or so and get a custom grind, such a cheap piece, and determines so much about your engine. If you left that cam in there might as well go with 185's and save some money

Haha, good choice. I dump over a years savings into just then engine of this car keeping it EFI. Could've knocked off about 4 or so grand if I went with a carb
