So which heads will get my 358 in the high 10's

[mt-engines]

What are your 60 ft times and at the 1000 ft mark?

How much does the car weight?

Also what rpm are you leaving at?

What rpm is the motor doing at the 1000 ft mark ?

Exactly. Is this a 2400lb door car, or a 4600lb truck?

Its hard to understand what you want without giving us enough information.

Excuse my Drag racing ignorance, wouldn't we just need to know min to max rpm used and whether traction is a big issue or not ?
If he turns it from 5000 to 7000, we'd recommend the heads we think will make the most power over that range.

[ChopperScott]

I'd personally go with the AFR heads.

What's the race ready weight?

I know the AFR 195 have a good reputation but I thought the 210 was to small in the pushrod area

My reasoning is this...

Cast Iron vs Aluminum? Aluminum
49cc vs 65cc on pump gas? 65cc

60ft. is 1.55
foot stalls to 4400rpm
car weights about 3240 with my sbc
at 1000ft the rpm is around 6400 hits the 1/4 at 6900 right now with the 4.88's

I am sure my 8" 5200 converter will knock a little off the ET. Not sure how much the Ported Vic Jr. will pick up over the Air Gap with a cut down divider.

id slide a 383 shortblock under the heads/intake.

Surprised you're the only one suggesting that. As everyone knows the cost to build the 383-385 is the same.

Thanks for the requested info, and I will reply back when I have more time later, but I also have a general question for everyone one here.
Why is it that so many folks participating in brackets always post up with questions as to how to make more power and go faster when the goal for any changes made to such a car should be oriented to producing better consistency, right?

I always seem to walk away scratch my head from post like this!

Bragging rights are great in terms of ET numbers, but being in the winner’s circle means more to me!

I don't know Bob personally but I do know he has a lot of small and big block chev combinations he runs in his camaro.

MAG-
Some of us like to test different things on our street / bracket cars to learn,
Some of us don't really care much about a plastic door stop ( trophy)
Some people on this forum find these results that us budget hobby guys put up interesting,
Instead of walking in circles and scratching your head put up some relevant information to the question or don't post .
I was going to put up my track results from last night but why bother,I would hate to be bragging.
Rant over

I will say this, I go out to have fun and beat up on as many late model cars that I can with my junk combo's. For me running a pump gas .040 350 in the 10's was unheard of years ago, same thing could be said about my 461 BBC peanut port engine in the same car that ran 11 teens with a nothing compression engine. Also, I hate bracket racing and do not go to those races anymore with people who can't race with their skills and race with a ton of electronic gadgets, kind of like S/C and S/G, it's like watching paint dry when they race and that boring for me to watch. When I go to an event I love watching Stock and Super Stock cars, they're super cool. When these tracks make a green and go bracket race for sure I will race it. Right now I just race Muscle car events as it's heads up and you can live or die by your combo.

Now back to my 358 combo, I checked the chambers on my other 350 block and the chambers are only a tiny bit bigger in one spot so they should work. I may just try them for sheets and giggles. Only cost is a few gaskets.

I see this all the time, trying to get a lot of hp out of a 350. I've been there myself. I had a 355 in my car and thinking about what I could do to go faster. I repaired the spun rod bearing in my 406, used the heads manifold etc from the 355 and it was a full second faster.

[Little Mouse]

There's always quicker or faster either someone else engine car combo or your own. There are those that think a 406 sbc why are you waisting time with that when you can use a bbc for drag racing. Its all about the fun factor in doing it whatever you choose for an engine.

[rfoll]

Not to make any criticism of the OP, but I'm all about going faster without spending a fortune. I'll vote for the AFR heads and the 300-25.

Yep, well said. And we all have to remember O/P post #1 “I would like to push this engine into the high 10's as it's a small goal I have right now”. Suggesting upgrading to larger cubes focuses on the “high 10’s” part of the goal, which isn’t necessarily bad but ignores the “this engine” part. There is a bit of a subculture of us weirdos that enjoy taking on testing, refining and developing what will be challenging to meet our final goals. A 358 into the 10’s without any exotic parts or fuel? Or a 383 with less than 2.02” valve and 190cc heads in a 3600lbs street car in the 10’s? I’m sure it’s been done before but taking on those challenges would get me out of bed every morning before throwing cubic inches or big dollars at them. Which is not wrong by the way.

To the op I think if I were lucky enough to have a set of afr competition 210 heads would use them with whatever manifold you have so far found to work well.

None taken, my goal is to get this 358 engine in the high 10's on it's own as I have 2 406's that run mid to high 10's anytime I want to. This little engine has been 10.04@136mph with a 200 shot of nitrous in the past and while it was fun this little engine was only running in the 11.70 range N/A at that time, so it's come a long way. I just need a little more to push it over the edge and even if it's a 10.99 I can always say it ran a 10 sec. time N/A.
