You might consider getting an all mechanical distributor (no vac advance). Small block chevies usually make max power on about 36 deg total timing. Some a little less if they are running the vortec style cylinder heads... but I digress. If the distributor has 24 degrees of vacuum and mechanical advance, then setting the initial timing to about 10 degrees will put you in the ballpark.

mike100

also the vacuum advance won't contribute anything at WOT, so you would need to compensate for that. Adjust with it disconnected or eliminate it.

All that's going to do is **** away the guy's gas mileage and heat the hell out of the exhaust valves.

how old are your tires?

225 radials, yeah you should probably get 275 or larger and maybe even go drag radials. Did you make a mistake? In my opinion, not at all unless you could have went larger. Use your right foot to limit the initial. they can make a 1000 horse hook on 10.5" tires, you should be able to hook with a set of 275's. A single plane intake would help reduce low end and Worse case scenario you could always use too large of a cam to reduce the low end. But as i mentioned you should start with larger tires and when you go to the 700r4 the low first gear is going to make traction even more challenging.

It's not too much horsepower. It's too much right foot. Get better tires and learn how to control the right foot.

i just put a set on mine and actually it handles better than the cooper cobras that were on the car. i suspect they will even be better in the rain. those cobras supplied NO grip.

i knew richie years ago when he was dominating the pro-stock class, he is a great engine builder, one of the best. last i heard he was building boat engines. if he was involved your cars a Runner.

Or 1.5 rockers. The carb will only take a little off the top end.

I finally just gave up on 15" street tires. Just ordered some 9.5" Coys C5 with Bridgestone Potenza RE-11s, summertime only baby!

I think that reducing cam size and or carb size will only add to low end, if traction is an issue and tires don't cure it, then you need to take away from the lower end. I still think that wider tire will do wonders for the traction issues.

And theres no such thing as too much power, just too much happy pedal. Put new tires on it and learn how to drive it. I imagine the tires you have on it are rock hard and old and a stock L48 could spin them

7t9182 i would never ever say anything about richie Zulll on this forum every body would label me BS. however i was there and saw it with my own eyes at NHRA nationals.the pro stock boys hated him and threaten our life`s if we were not out of town by sundown. exactly like taking your wife`s car in the garage work on it go to Daytona take a lap and qualify for 50th pole position then win by a car length.no sponsor ,plane white camaro with his name on back of car look like he drove in from parking lot ,starting in last place round robin so he had five times the runs on that engine as any of the leaders turning over 1000 rpm more then any other car beats Chevolet sponsored Warren Johnson on final run.----ridiculous how is that possible 498" big block one four barrel.final Dyno run at 4am before installing in car and nobody saw nothing 1834hp at way past 9000 rpm.!!!I am not even going into the APBA boat racing and not many people would comprehend a race boat that never lost or even place second finally the "the boys" burn the boat while on the trailer in the pits. no more discussion he is gifted and thinks way out of the box.

Captain bob

thank you blue dawg i was considering installing a Holley 600cfm i have but you are right it will just take away from top end i will go with 275/r-15 hopefully i will not raise height of car at rear as of now it is 1/4" higher in rear.the motor showed 565hp on first pull i was not happy so we removed single plane high rise manifold with 11/2" spacer along with that other cam i mention took hp al the way down to 516hp at 5600. i will leave it at that and learn to drive like he said Captain some of us go with .02 reaction you may need one minute to figure the lights went from yellow to green!

garygnu

you can find many different drag radial tire sizes meet your needs .do you have a 3310 vac -secondary carb on it ? thats what I see in the pics of the motor .if so put a very stiff spring in it to slow down the opening of the secondary .also consider better shocks and springs to help transfer weight for better traction .

Captain bob

the carb is the new Holley HP 4160 750 cfm -vacuum secondary.the " right" carb is a 830cfm on high SP high riser and for us old folks with one foot in the grave a 600cfm might be the ticket. i know nothing about tires and what fits under stock 71 body but i am going to learn in a hurry.the shop has a beautiful "white room" for final assembly there is a photo of a c-5 that turned 6.93 1/4 mile."he can teach you"-------no thanks i would have a heart attack.

No such thing as too much power... That's an oxymoron. Sacreligious to even say it...

The whole point of building hotrods is to have a lot of power you can cruise with..

I'm about to drive my 10 second car cross country with no OD for crisssakes..

Build em, race em, DRIVE EM!

He Pissed off Bill Jenkins when he went out and whipped his butt with the car he leased from him.Richie Zul is one of the very best,and his record stands on its own. p.m. sent

Captain bob

GOD`S honest truth some dud from LA. walks up to us in pits after some friendly talk and a beer he told richie " there going to shut you off at line"NHRA Requires a exposed shut off switch at rear of car if a official see`s a fuel leak he shuts you down at starting line you are disqualified.we bypassed switch before going to staging area .sure as sh-t that switch was turn off when the car came into pits! "he never paid his dues".

Captain bob

holley 505 i like those 275/r60/15 MT. do they fit under wheel well without back spacers? would you happen to know the diameter?trying to match 27" diameter of front tires.---thank you bob

Rebelrob

I do not see that you have a problem....
Imagine BB torque.... even worse...
