On 71 and 72s there are 4 that hold the upper radiator plate on and I have seen them on the upper latch striker on the hood itself, 3 of them, besides the hood latch where you have them. 12 in total ,12 point bolts. 3 on the hood, 4 radiator plate and 4 for the hood latch. (2 to the rad support,2 to the tie bar/grille support and one to the support on the pass. side that holds the horn. Regular 6point bolt on driver's side horn if a dual horn car.)

Ok. Thank you for that info. Put the engine back to the dyno sheet specs. Total of 35 degrees of timing, the 770 carb and NO vacuum advance. Your timing is probably off the chart advanced making the car a pig. Set everything back and I can almost guarantee a totally different car! For the better!

What carb was the engine dynoed with? Put the timing back to his specs and try from there. You will probably be happy with the results. He had it set for best engine performance and power. When you reset it, those dyno figures went out the window.

Happy Thanksgiving to everyone! Big or small or no gathering I hope everyone is safe and happy! This is the holiday where my family usually swap cars or projects. Lolol

Thanks for the info. Is this a vortec pro engine? The numbers are good but normal for a peanut port big block. Meaning alot of torque and out of steam at lower rpm. With a normal size oval port head and a 468 cube big block 5500 rpm should be no problem. That being said and what you said I would first try bringing in the timing curve down to 2000 ish. What distributor are you running? Any quadrajet roughly is 750-800 cfm. Depending how far the secondaries open. I would see if anyone you know has a 650DP holley you can try. From your description it sounds like it is drowning on itself. Have a friend that just installed a vortec pro 468 into his Monte. Dynoed at the same numbers as yours only with oval port heads and a 650 quick fuel holley style carb. He says it's better on gas than the 355 small block he removed. He is running a th400, 2500 stall and a 3.73 gear and can smoke the tires at will. Edit: do you have the dyno sheets? Why did you change the timing? Before anything, reset the timing to the dyno specs and go from there. You may have too much timing and that's why the engine is flat. 530hp and 600 ftlbs should be fun to drive!

You are more than welcome Rob. Extremely sorry of the outcome. 😖

😡🤬😤🤬🤬😡!!!!!!

Ahhhh. LS turbo swap. Lolol. Ok. I just didn't want you to spend extra coin that you could use to upgrade your engine in it now.

Hi. From what you described, at the moment, I don't see the need for 33 spline axles or a c clip eliminator kit. Your 402 won't break it. I do recommend the detroit trutrack. Every one of my running Monte Carlos and my son's Monte plus his GTO have one. Also running strange 30 spline street axles with the c clip. My red 70 has a 496, th400, 3.31 rear and has been ran at least 30+ times down the 1/4. No issues what so ever. The GTO has a ram air 3 400, M22, 3.73 and a 24yr old behind the wheel. Nuf said. Lololol His Monte just recently went to the track and was running 13.20@103 with a super mild small block and 4.10 gear. Building a big block now for it. The rear will stay the same except gears. Going 3.31.s What is your cars combination?

Welcome! Beautiful SS!

Are you sure you have peanut port heads? What cubic inch is the engine? I was not aware the RPM intake was made for peanut ports. Only oval or square/rectangle port. If you have an oval port intake on a peanut port head the transition between the two could be your issue. Fuel puddling between the head and intake. What size holley avenger did your engine guy recommend? What's your timing set at? Cam specs? Converter size? Gear ratio?

Ummmm, whose site did you look at? Why are you not happy with the holley?

Tom, if you zoom in on the last pic, you will see very little space between the tire and what's left of the outer lip. The wheel wells are rotted on my son's Monte also. With the rim you mentioned, it will be 1/2" towards the wheel lip MORE than the one pictured on my son's Monte. Can you make it fit, sure. But will it be worth it? My "guesstimate" would be that you would have to trim the wheel lip flush with the outer quarter panel and it still MAY rub. Truly only one way to find out. You asked for opinions... Eagerly await pics. 😁

Doesn't matter on the tire manufacturer. All basically the same dimensions for the same size tires. The 5 inch backspacing is your issue. Even with a 275 you will most likely rub bad on the quarter panels. My son has a 275/60r15 on a 15x10 rim with 5 1/2" backspacing.

Love the story! Get her up and running and enjoy her!!! Too many good memories!

Welcome! Beautiful Monte to represent down under!!!

Cool story. Nicely optioned. Would love to read about how you got it. What about just making it road worthy and enjoy it again?

Welcome Ron! She's a beauty! Any pics of the interior? What options does she have? I see the fiber optics for the washer fluid but no air ride pump. Pics of bad areas?

Welcome Leni! Sorry to hear about your dad. Interesting story about going to and coming home from the hospital in a Monte Carlo. We love pics here!

Rest in peace Jim. My prayers and condolences to the family. 😓

Lol that's how the "collection" or "in stock" starts... Will we ever stop? Lolol NO! Congrats on the latest acquisition!

Welcome Clifford! Nice looking SS!

Welcome Ed! Nice looking Monte indeed!

Is it that big of an issue that the neutral safety switch has to be in the console? Can you leave it on the column? Then with the backdrive from the trans to the column will work the switch.

Welcome to the madness Johnny! Look forward to seeing more pics!
