most do not know exactly what their measured compression is
and
they lie about it
Unless class racing with no fuel rule
I'd rather have to little than too much

This is what I ordered.
255/265 .640/.627 on a 106 sep.
Guess I will wait and see what it runs later in the year once its all together.

After months of test fitting, assembling, retest fitting and buying more parts... Its finally in the car and running. No issues so far other than a few leaky head studs i think some block sealer took care of. If the weather holds out tomorrow im gonna find out how this thing runs.

[wyrmrider]

looking fwd to your update
thanks

Update, a windy day caused the track to only allow 1/8th mile racing. 20 to 30 mph head to crossing winds were pretty bad all day. It would blow my dads hat off his head while putting me in the water. Long story short my best pass was a 1.36 60ft, 4.11 330ft and a 6.50 @ 99.1mph on the brakes in 1/8th. My time runs it was going 102 mph. Everything went well other than the rear main seal is leaking, gotta pull the engine out again. More work for me and pops. Guess I will not buy no name seals again. Felpro from hear on out.

Had a customers build 434 pump gas with a custom roller made by lsm .649" @ 109 lsa ran really well @ 3300lbs 10.16 132 with 4.56 and 28/10's. If memory serves me i Believe we went 6.3's of the foot brake 1.47 60ft cam was very mild and streetable also 1000 cfm pro systems 4150 with no tuning on 93 pump this combo should have been good for high nines all day with some tuning only had 28 degrees locked dizzy

Well changing carb is something that you can try later on when you are at the track. One old dragracer told me many years ago: Dragracing is about making as many hp as possible at the shift recovering point, not hp at peak rpm.

I am just a student so, i thought you want to shift at the same HP as the recovery HP for each gear so as to utilise the most area under the HP curve. Just thinking.

6.50 on the brakes is pretty good at 3300 lbs...

loktite 518 is needed for the rear main seal splits.

Got the main seal issue fixed, while it was apart found a defective timing cover. The trough the pan seal fits in was spot welded to the cover and was broken loose only holding by one spot weld. A few tig tacks and back in buisness. We also retarded thecam 2 deg while it was apart. I lost 2 to 3 hundredths in the 60ft but went 10.43 @ 127 in the 1/4. I gained 1 mph in the 1/8th so i think it may have helped some.

[wyrmrider]

sometimes when that happens you can run a shorter tire or gear and get the best 60 ft and 1/8
try another 2 degrees- I have a hard time finding 2 reliable- when you've gone to far then back up a little

I have never heard anybody ever say ,, " I had a 372/377 , and I hated that d@=- thing " ,, people with em like em ,,, some folks just have a hard time with that ,,lol ,, , I hope u did at least a low pour on the block

[cgarb]

No, the block isnt filled. The bores were finished was one reason, and i run block heaters. I was going to run this shift this engine at 7k, it really don't seem to need it. If i shift at 6800 it traps at 6500 on the 1/4. I probably could shift at 6500. Maybe i will try that next week.

" main seal issue fixed, while it was apart found a defective timing cover. "
amazing how those timing and valve covers can cause rear main seal leaks
keep good notes, waiting to hear how you do next week

[cgarb]

I'm not sure one caused the other for sure. The timing cover wasn't leaking yet...but the rear main seal wasn't a felpro. It said for a 400 sbc line hone but it didn't fit as snug in the cap as the felpro replacement that didn't leak. Glad I caught the timing cover for sure...last thing I would have needed was the piece of tin to get wrapped up in the timing chain.
