Hello everyone! I am looking to build a 350 to go in my 1973 AMC gremlin for my dad who has recently been diagnosed with a terminal illness. he had one back in the day but had to sell it shortly after for financial reasons.. Hes always been a hard worker and he deserves to be able to drive one once again while he is here.. Im working long hours to make this happen so cost of good parts hasnt been a big deal... also the gremlin has been tubbed out for wider tires.. I already have a narrowed 9 inch ford rearend with 3.73 gears and posi installed in the car with a custom made adjustable four link setup.. And a brand new B&M bulletproof series turbo 400 transmission...

what I have already:

010 casting 4 bolt 350 bored to 0.40 over
Eagle 4340 forged steel 3.48 in stroke crank
Eagle 4340 forged steel h beam rods
ross racing forged aluminum flat top pistons
Holley 850 cfm double pumper
 a set of 461 hump heads

I got the 461's in trade that had never been touched..still had the original 1.94/1.50 valves... I know a guy who has a machine shop and I had the heads ported extensively and polished.. 2.02/1.60 SS valves, screw in studs , guide plates, hardened seats, the whole nine yards.. he only charged me 500 bucks.. I know there are better heads out there but my old man had a set done up just like them and it tickled him when he found out that I found another set and had them fixed up...just the smile on his face made it all worth while... I do not however, have a cam or an intake chosen and would like to know what you all think would be my best choice and what is the best hp/trq I can expect out of this combo?

I would use the dual plane for a street car and the single for a dual purpose car.
You will lose some hp with the dual plane but it will be more streetable.
I would guess your hp would be in the 350-400 range depending on cam, builder, tuner, etc.

I think the 850 DP might be a bit much for the street on a dual plane.
For the strip it will be great with a single.
I would opt for a cam, carb and intake that offers a good compromise of torque and horse power.

I agree, trade that 850 for a 650 and that will be plenty for a light little car. A good dual plane manifold will work just fine unless it's going to be a race car only. Look at cams in the middle, too big and you will not get into the power band just driving it around.

I watched the video. The first one in the drivers seat sure brought back my racing days. I wanted to get back on the track right now. Lots of good times remembered, especially in the low 7 second Beretta I had.

i appreciate all the input guys..okay so I need to get a 650 and a dual plane.. I know it needs to match the rpm range of the cam I choose but I couldn't find any info on the gmpp 218/228 cam.. anybody know the lift of this cam? rpm range?  I have looked at so many cams I just am unsure which would best suit these heads..and just for clarity is this 010 block a first gen block or second gen?

I have a Edelbrock 625 AFB if you guys think it would be useable.  That sucks man.  I lost my dad in 09.  Let me know if you can use it.  It's an older one, still has the Carter High Performance label on it.

 the 010 block should be first gen.

heres a cam i would consider.  i'm sure you could end up with many recommendations.

heres an intake i would consider.

heres a program from comp cams that might help a little in cam selection.  nothing is set in stone, but it should be a lil helpful.   you can add all your info from your combination and it will give you horsepower & torque potential numbers.
